How can i set the path in java program?

I installed jdk1.5.0 update 2 and wanted to set permanent path so that i can write programs in java but when i wrote javac in command prompt answer was ' javac is not recognized as internal or external program.

How can i set the path in java program?
i'm assuming you're on windows. If you are you can include the path to this .exe in the path parameters.





From the command prompt:


set path = %path%;[path to folder containing .exe]





i'm not sure how to do it on other platforms, but it should be something similar regarding setting environment variables
Reply:I think it is good to make sure you type in the path correctly. It want to tell you about .bat file. I will automate your coding.





Open Notepad, type in:


javac C:\Program Files\Java\jdk1.6.0\bin\javac MyClass.java





save that file as "compile.bat" into your folder with your current work project.





Start another file in Notepad, type in:


java .\;C:\ProgramFiles\Java\jdk1.6.0\bin\jav... MyClass





Note, just after java the .\; that is look here first, java, this folder. The semicolon is the DOS end-of-line. The rest is the path to the java engine, a space the Java program you compiled.





Save that as "run.bat" in the same folder.





Now, you can double-click the .bat file. If it fails, make sure the path points to the bin folder inside JDK folder. It can be tricky. You see, in DOS the folders are \ (backslash). In java, in the internet, everywhere else, the path folders are "/".





If you .bat files work, great. Change your environment variable. You can then make your next bat files without the path.


javac MyJava.java





java MyJava





And finally, the NetBeans IDE does this bat file automatically for you every time you run code. NetBeans is a great editor, colors the keywords and helps you code.

How do you compile Java to native code?

I hate Jar files, classpaths and the JVM. All Java desktop programs have unacceptable startup times and huge memory footprints. I have searched for ages and found not a single no-nonsense method to compile Java to native code, so I'm seriously considering to desert to C# and .Net, just because of that. Do you know of any solution?

How do you compile Java to native code?
I think thats just a downside with Java you gotta live with if you use it.. just as the downside of C is that it would have to be compiled seperately for any different system you'd wanna run it on. im sure there are better languages out there, java was never designed to be user friendly in the first place!
Reply:lol you think that stuff is bad for java, try a language that doesnt even compile to bytecode
Reply:You can use the ANT tool to do the process of compiling java files and create a jar file. It also does some other stuff. Just check it here:

if the files are in torrent format, you need to download the actual java game using a program called bitTorrent.





then once you have the java files, transfer them to your phone with a USB cable using your phone's software. if you dont have it installed or lost the cd, you can download it from the sony erricson website.

How can I get the greatest integer in an array in Java?

I have a variety of integers in an array. How can I most easily find the greatest one among them?

How can I get the greatest integer in an array in Java?
This should get you started:





// algorithm to find and display largest item in array





int largest = numbers[0];


int pos = 1;


int SIZE = 10;





while (pos %26lt; SIZE)


{


if (numbers[pos] %26gt; largest)


{


largest = numbers[pos];


}


pos = pos + 1;


}





The variable "largest" contains the largest integer.
Reply:therss no greasted interger
Reply:int largest = arrInt[0];


int ctr = 1;


while ( ctr %26lt;= arrInt.length-1)


{


if (arrInt [ctr] %26gt; largest)


{


largest = arrInt[ctr];


}


ctr++;


}


System.out.print("The largest integer in the list is: " + largest);





//largest is the variable that will hold the largest integer.


//arrInt is your array


//arrInt.lenght determines the size of your array.
Reply:either loop through them and do:


if (number %26gt; highest) { highest = number; }





or use Array.sort() and get the last element. (much slower)

What is a good way to make a sparse matrix in java?

The matrix could be large (10,000 by 10,000), but very sparse. I plan on doing a decent amount of calculations with it. What data structure/ library should I use to do this easily?

What is a good way to make a sparse matrix in java?
There is a library to do it. Usually the code that most people write won't be as efficient as the code in libraries.





http://rs.cipr.uib.no/mtj/





http://www.ii.uib.no/forskningsgrupper/o...
Reply:The easiest way is probably just to use a Hashtable. You can use an Array of Integer values as the key if you want. Then the "size" (or maximum index values) does not matter much at all, as well as the number of dimensions.





http://java.sun.com/j2se/1.3/docs/api/ja...
Reply:Well, i suggest to use the Coordinate Method Representation, in the case that you have multiple elements per row you may use the Variant Coordinate Method Representation, but anyways try to make your work done on rows not columns, since none of the previous representations is efficient if frequent colum operations are required.

Its good that you already know C++.


So you won't find any difficulty on starting with JAVA.


For that you need to download Java Software from the authorised website of Sun Microsystems.

Reply:Chetan has you on the right track, and you should have no problem with Java if you know C++.





Chetan has already answered your question, I'm just thought I would throw in some comments. The creators of Java were certainly thinking of the C++ programmers when they created it. It is very similar. The nice thing about Java is that the compiler IDE everything is free. I like the NetBeans IDE myself. You can even get the NetBean IDE with the 1.6 (1.6 == 6.0) JDK as a bundled download (Java Development Kit, ie the compiler and libraries).





Note you will see Java SE (Standard Edition, desktop apps), Java ME (Mobile Edition for phones and such), one for Web application, and Web backends, databases. Tons all from Sun.

What is the importance of learning Java in Electrical & Electronics Engineering?

I am a student of EEE. I want to go to communication sector in higher studies.


My friend told me about learning Java.


I want your opinion if you know the importance.

What is the importance of learning Java in Electrical %26amp; Electronics Engineering?
actually java is not the thing for eee. its better for software development, strictly object oriented, has support for state of the art development methods and patterns. main feature is that -- java is platform independent. as a eee student you will need low level access to the computer --- java will not help you much, if you are looking from academic side.





for a quick (10 min) intro, how java works, read this :


http://www.geocities.com/hellopopel/J10M...
Reply:If you have some knowledge in C and C++, tou should IMHO make yourself more proficient in those, and not waste time on Java unless it realy interests you - as an electrical engineer, you should probably have some basic understanding of programming languages, but you probably have more important things to study that are closer to your field of expertise.
Reply:Electrical engineers are also asked to create or write softwares for the hardwares that they develop using high level programming languages, and java is one. jave is one of the most commonly used programming language to implement business applications to day and even with every commercial lines. with the use of java, it would probably more easier to write in code the algorithms and logic that you would want to implement in your hardware design for the chips??????? im not sure though if you are really into creating software applications for the hardware or the chips you create....
Reply:It depends on what you want to get into in the communication field. If you are thinking of doing embedded applications then C or C++ would be better. If you are just going to do hardware engineering, then you dont really have to know a language, but understanding microprocessor interfaces are very important, so knowing the basics of programming helps.
Reply:I think C++ %26amp; java is the besic consept in a program so .........





it is the very very important four u
Reply:Java in some applications, such as on the desktop, can be totally unnessesary because of it's JIT system (compile and run when user opens). However, I do remember that there are a few Java firmwares out there for lego robotics (RCX). Otherwise, it may have been suggested to you because it does compile at runtime and therefore is cross platform.





Lastly it may be because Java can handle complexities, but then again... I have not programmed Java before so I won't know about how efficient it is.

What is a internet browser java script error?

On my computer I use the sbc dsl internet browser and it will randomly put up a 'java script error'. The computer then freezes and wont let me on the internet anymore. Why is it doing this and how can i fix it?

What is a internet browser java script error?
Those error messages normally don't have anything to do with your computer or internet service. It usually means that whatever website you're trying to access has problems with its coding. So it's not something you can correct, it would have to be corrected by the people who did the programming for that site. If you can access the site you could look for a "contact us" or "support" link and bring the problem to their attention. If you're using IE7 the problem is even more wide-spread because IE7 isn't recognizing a lot of the older programs.

Can you give me a Java console that find a specific word in sentence each line from file?
Take a look at the methods on the String object. In particular, consider using the indexOf(String str) method inside a conditional statement. Also keep in mind that a sentence can contain the work you are searching on multiple times so you may want to look at using the substring(int beginIndex) method to temporarily walk through the string so you can find the duplicates.

At worst, you drafted a team based on default rankings.

If you truly love fantasy baseball, don't let something small like not being able to add your personal touch to the team stop you.
Reply:You can't drop the team now. They won't allow it because it would mess up the league. You can still trade and still have a shot of doing well. You may have a better team than you think.
Reply:In my experience you can not drop out after the draft. You could always just not compete, but that would be a disservice to the other teams in the league.

I need some information about James Gosling, who invented the Java programming language.


Or, you could give me a famous candian person other than Celine Dion, Jim Carey, and that hockey guy. Thanks

Does anyone have information about James Gosling, the inventor of Java programming?
Dr. James Gosling , Ph.DJames Gosling, Ph.D (born May 19, 1955 near Calgary, Alberta, Canada) is a famous software developer, best known as the father of the Java programming language.








Education and career


In 1977, James Gosling received a B.Sc in Computer Science from the University of Calgary. In 1983, he earned a Ph.D in Computer Science from Carnegie Mellon University. While working towards his doctorate, Gosling created the original version of the Emacs text editor for UNIX (gosmacs), and before joining Sun Microsystems he built a multi-processor version of UNIX, as well as several compilers and mail systems.





Since 1984, Gosling has been with Sun Microsystems, and is generally known best as the father of the Java programming language. Gosling is currently (as of 2006) Sun's CTO of the developer product group.








Contributions


He is generally credited as the inventor of the Java programming language in 1994. He did the original design of Java and implemented its original compiler and virtual machine. For this achievement he was elected to the United States National Academy of Engineering. He has also made major contributions to several other software systems, such as NeWS and Gosling Emacs. He also cowrote the bundle program that you learn to make a version of in Brian Kernighan and Rob Pike's book The Unix Programming Environment.

I don't know if you are familiar with the Problem-Based Learning (PBL) style, but if you are anything like me then PBL is a really good way. Basically I have looked at a few online resources to get a grip on Java and then jumped straight in. I meet a problem and then I look it up on the internet. I haven't paid a single penny on a book to learn it, but I would recommend some reading before you start.

What are the differences and similarities between Java and AS3?

i saw some of the syntax os AS3 they are kind of similar to Java.


Are they some what alike?


is it easy to learn AS3 if you already know Java?





Thanks!

What are the differences and similarities between Java and AS3?
ActionScript was released into the public domain and is currently being debated as the ECMA specification. ActionScript is more akin to javascript than to java.





ECMA, if it comes to be, and if Microsoft can accommodate it, will make for the first time, a universal scripting mechanism for all web technologies.





Java, also, has been released into the public domain with the hope for wider adoption. Java is capable of running cross-platform. ActionScript is not supported on the Linux platform. Java is supported on Linux and others. Java also incorporates the ECMA script standard as part of the java API. java is compiled bytecode.





As far as learning AS3. It is the same as javascript with a little stronger data typing. AS3 is part of Flash and the strength of programming AS3 comes from the graphical timeline in the authoring mode of Flash.

How is the max value that you can set with the -Xmx param for heap size of the java jvm determined?

I would like to instantiate the java jvm with a larger max heap size. I use the -Xmx parameter to do so. I have discovered though that the value you can specify here differs from box to box. I assume its related to the physical and swap memory. Is there a formula that can be applied to determine the max value? Can you get around physical memory limitations by instructing the jvm to utilize swap memory (I am using linux)

How is the max value that you can set with the -Xmx param for heap size of the java jvm determined?
According to Sun's documentation, the defaults are set as follows:





If not otherwise set on the command line, the sizes of the initial heap and maximum heap are calculated based on the size of the physical memory. If phys_mem is the size of the physical memory on the platform, the initial heap size will be set to phys_mem / DefaultInitialRAMFraction. DefaultInitialRAMFraction is a command line option with a default value of 64. Similarly the maximum heap size will be set to phys_mem / DefaultMaxRAM. DefaultMaxRAMFraction has a default value of 4.





Anyways there is no way to utilize swap memory. All heap increases use methods that try and avoid swapping.


Also heap increases and decreases can be controlled by the


-XX:MinHeapFreeRatio and -XX:MaxHeapFreeRatio options


which looks at the ratio of free space to object space and makes sure that it lies between these option values. Defaults


are 40% and 70% for above ratios respectively.





Otherwise you can try to use the -XX:+AggressiveHeap option to allow the jvm to push the heap to the limit, again unfortunately limited by the physical memory. But key issue is setting max values will also affect other applications running on the server so setting the correct value will depend on what the required service level is.

I want to write some small programs to automate tasks between Excel and Access. Should I use VB or Java?

I do a ridiculous amount of running queries in Access, copying and pasting data into specific cell ranges in new date-named worksheets in the same workbooks every week. To add to the issues, I pull data into my Access database using ODBC-connected tables that require me to login to the server with the same login info using the Linked Table Manager everytime I load my Access. The copying and pasting to specific cell ranges in specific worksheets in one workbook. I need to automate as much of this as possible. I already know Java and know that Java could simplify a lot of the repetitive tasks, using a good API. However, I want to avoid having to go through downloading the files, programs, etc. necessary to run Java apps on my work computer, as I want other co-workers to be able to utilize the same program that I come up with on their computers without a lot of hassle. I don't know VB and am still unclear if this is something I should learn that will work similar to Java.

I want to write some small programs to automate tasks between Excel and Access. Should I use VB or Java?
It depends on what database driver the ODBC connected tables are to. If it is a MS product (more likely the case), then VB and VBA are what I would recommend. The libraries would be easily available in VB to drive and automate applications to connect in this fashion.





If you find it is non Microsoft, then I would use Java, which means you will need to potentially write your own application to perform the functions stated. Java does not really easily integrate into MS applications

if you want total control over what gets exported to excel, use vba code. Include the Microsoft Excel Object Library in References so you are able to read and write excel files in a module.

Dim xlBook As Excel.Workbook


Dim xlSheet As Excel.Worksheet





' Export a recordset to an Excel file


' mb - November, 2001





Dim CName As String


Dim X As Integer


Dim c As Column


Dim fld As Field





rs.MoveLast


maxrows = rs.RecordCount


rs.MoveFirst


myrow = 1


mycol = 1


Screen.MousePointer = 11





' load Excel


Set xlApp = New Excel.Application


Set xlBook = xlApp.Workbooks.Add


Set xlSheet = xlBook.Worksheets.Add


xlSheet.Name = WkBookName





' Output the field names


maxcol = rs.Fields.Count


For mycol = 0 To maxcol - 1


Set fld = rs.Fields(mycol)


xlSheet.Cells(myrow, mycol + 1).Value = fld.Name


Next





' Output the data


myrow = 1


(remainder of code is not shown)


You'll need to just bump through each record in your recordset (rs), retrieve the field data, and write it to the excel file.

Use the "TransferSpreadsheet method " in ms access if you just want to move ms access query results to Excel with no checks and balalces..
Reply:Between Microsoft products, your best bet will be to use VBA, VB, or C#. You can use Java working with a Java to COM bridging framework (JIntegra for example) but it definitely adds a layer of complexity. Unfortunately the errors thrown in the Java/COM bridging are not very useful (at least based on my experience).
Reply:I would strongly suggest using VB, simply because both Access and Excel are Microsoft products, and there are several libraries included with VB (.Net anyway) that allow for fairly easy linking to both the Access and Excel object models. If you know Java, you should be able to pick up VB quite quickly. It is more literal than Java, more wordy, and if anything, easier to program in. You might also consider putting the code directly in Access, in the VBA behind the forms and reports. Most often, in industry, that is the method I have seen used for working between Excel and Access. By the way - if you are having to login to the db every time you access the linked tables, it sounds like they may have been linked without the "remember password" box checked. When setting up the linked tables, there is screen that comes up when setting the ODBC connection that has a small checkbox in the bottom left side that says "remember password" or something like that. If you go back through the process, and check that box, you shouln't have to login every time. I experienced the same problem, and found it easier to spend the time recreating the links than to have to login every time. Good luck - if you need any assistance, I'd be glad to help : )
Reply:Hi,


this should be easy just use "VBA" in your excel file, search the help files for using "ADO" links, which will let you connect to other programs remotely and select what data you want and paste it where you want as well all for you.. hope this all helps you. a good book is MS Office "Inside out" if you need more help.
Reply:Hey, i'd use vb in this example. Keep it nice and simple and you cant go wrong.

Why does the Java applet start running in my bar where the clock is when I just go to a website?

Any website that I go to, it does this.

Why does the Java applet start running in my bar where the clock is when I just go to a website?
Your browser is set up to load the java applet or the java quick launch. If you stop it, some pages may not work. It the settings you should be able to set it to load only when needed or at least turn off the icon in the system tray
Reply:Normally, when you go to any website that has java running (so basically you need java in order to make the webpage running properly in your PC), if you have java, it will run automatically. it's normal, don't turn it off.
Reply:Some web sites require a much more powerful version of Java than the basic version supplied with Windows. The applet will appear when a site is accessing JRE (Java Runtime Edition) or JVM (Java Virtual Machine.). This is normal. It means you have the most powerful version of Java installed on your computer, which is good.

I stink at java programming, should i still major in computer science?

i just took my first computer science course, in introduction to java. ill admit that im absolutely terrible. ill probably get a C+ in the course, especially after that last test.





anyway, would it be smart to just change majors, or should i stick with it?

I stink at java programming, should i still major in computer science?
Stick with it , It can seem overwhelming at first but give it some more time.
Reply:What is the reason you got a C+ in the


Introduction to JAVA ?





If you find it difficult to understand the logic


and language structure then its time for you


to move to another field.





But if you can comprehend JAVA given


more study time and better learning


materials ( books / references ) then


stay with the course.
Reply:I would have thought you would have received a C++ or C#. Boo! Yeah, I know...bad joke.





I have a B.A. in Computer Science and I find it odd that your first CS course is in Java. That is the wrong approach. You should learn C+ or C++ first, as this is the basis of most of today's computer languages including Java. If you are passionate and interested in becoming a programmer, I suggest continue with the major. But, I would strongly suggest taking a more basic course and speaking with a counselor or someone from the CS department.





My first CS class was programming in C. Then, I moved to C++, Postscript, Java, Javascript and ASP.

How do I clear my Java cache?





In order to delete the Java cache and objects, which is different from the browser cache and temporary Internet files; using the latest version of Sun Java 1.5.x, please follow these steps if you are also using Windows. If you are not sure if you have the latest version of Sun Java or not, please visit our article about checking for the Java plugin and follow the instructions.





Once you are sure you are using the latest version of Sun Java, please follow these instructions to delete the Java cache and objects if you're using Windows.





Click the following things in order: Start -%26gt; Control Panel -%26gt; Java -%26gt; 'General' tab.


Click the Delete Files button located in the Temporary Internet Files section.


Make sure all three boxes are selected, and click OK.


This should probably be done whenever you encounter a problem with the way a game is functioning. Restarting your computer after doing so can also help the performance of the game.





How do I install or update Java?





If you've never installed Java on your computer, you'll need to do so in order to play Pogo games. It's not uncommon for new computers (particularly those with Windows XP) to ship without any form of Java installed, so don't panic if you don't have it. Java is a free download and is easy to install. Also, updating it follows the same steps, so these are directions for that, as well.





Below you will find two sets of instructions. One is for uninstalling Sun Java and one is for installing Sun Java. Following these processes should help you resolve any problems you are encountering with Java, such as getting errors saying something like "Java Not Found or Not Working". The instructions below are primarily for Windows users. If you are using Mac OS X, please go to http://www.apple.com/java for assistance with uninstalling and installing Sun Java. If you are using any other operating system, such as a version of Linux, please refer to the manufacturer's website for assistance with uninstalling and installing Java.








Uninstalling Sun Java





If you already have Sun Java installed, or if you are not sure it is installed, try following these steps listed below. If you are unable to find the Java icon in the Control Panel as indicated, then go ahead and jump down to the second set of instructions for installing the latest version of Sun Java.








Click the Start button on the Windows Taskbar.


Select Run.


In the text box, type 'control' (without the quotes) and click OK.


Double-click the Add or Remove Programs icon.


Scroll down to 'Java Runtime Environment' or 'J2SE Runtime Environment 5.0' and uninstall all instances that you see.


Scroll down to 'Java Web Start' and uninstall it as well.


Restart your computer. To get back to these instructions to install Sun Java, come back to the Help Pages and do a search for "Installing Sun Java".


Installing or re-installing Sun Java








Go to the Sun Java Download page at www.java.com.


The steps may vary as Sun updates this page periodically.


Click the Download button that is usually on the right side of the page.


Click the Begin Download button.


Next you may encounter a warning message that instructs you on 'Installing the ActiveX Control'. Please follow the instruction to allow the installation.


If you see a Security Warning for installing the J2SE Runtime Environment, click Install.


Next you will be prompted to read and accept the license agreement. After reading the agreement click next to 'I accept...' and click Next.


When prompted, choose 'Typical' installation, and click Next.


When the installation is complete, you may be asked to restart your computer now or later. Choose to restart it now.


After your computer has restarted and you are online, go back and try to play again.


If you still have the same problems with the games after uninstalling and reinstalling the plug-in, please click on the 'Contact Us ' tab at the top of this page to request help via e-mail from one of our Game Support Representatives. Make sure to let us know that you already tried these steps, so that we can help you from there.





I got a "Java not found or not working" error.





When you first load a game, our servers run a 'check' on your Java to make sure it's working. A 'Java Not installed or not working' error usually means that something got messed up with your Java plugin or Virtual Machine and it's no longer functioning properly. If your Java's not working, the games won't work.





If you're getting this error, you should first try playing several different games. Here are some suggestions:





Word Whomp


Ali-Baba Slots


Cribbage (play with robots so you can leave if need be)


Ez-Win Bingo





If you get this error in all or most of the games, you should reinstall or upgrade your Java software.





If you only get this error in one game or a few games, you probably just need to re-download those games. Try clearing out your browser cache and Java cache as well, then completely close and re-open your browser and try again.





If you get this error and are using Internet Explorer 7, you may need to enable Java in IE 7.





'Java not found or not working' errors when using Sun Java and IE 7





If you recently updated to Internet Explorer 7 (IE 7.0) and are now experiencing 'Java Not Found or Not Working' errors, it is typically due to Java being disabled in the browser. You can manually enable Java using the steps below:





Open an Internet Explorer 7 browser window.


Click the Tools menu in the upper right of the window.


Click Manage Add-Ons and select Enable and Disable Add-Ons.


Click Sun Java Console.


Make sure the radio button at the bottom is set to Enable.


Click OK.


Close the window.


Open a new Internet Explorer 7 browser window and go to the Pogo website.


Launch a Pogo game.


Try one that you are sure was not previously working so you can test it.


Java should now be fully enabled and Pogo games should work correctly.





How do I make sure the Sun Java 2 plug in is enabled and working?





To check to see if you already have Sun Java installed and enabled, please follow these instructions.





Click the Start button on the Windows Taskbar.


Select Run.


Type 'control' (without the quotes) in the text field box and click OK.


Once you are viewing the Control Panel, there is panel to the left that either says 'Switch to Classic View' or 'Switch to Category View'. If it says 'Switch to Classic View' then click it. If it says 'Switch to Category View' then you are where you want to be. To the right of where it says 'Switch to Category View' you will see a list of items, the first item listed is most likely 'Accessibility Options'. Scroll down the list until you see 'Java' and double click it so the Java Control Panel appears.


In the Java Control Panel, click the Advanced tab. If you don't see the Advanced tab, you have an older version of Sun Java. To find out how to update to the latest version, please click here. (Once you've read the article, just click the Back button on your browser to come back here.) Once you do this, Sun Java will automatically be enabled.


Once you are in the 'Advanced' you will want to click the plus sign (+) next to where it says 'Applet tag support'.


There you will see a check box next to 'Internet Explorer' and/or 'Mozilla Netscape'. If you have Internet Explorer then make sure the box next to it is checked. If you have a Mozilla browser, like Netscape or Firefox, then make sure the check box next to the 'Mozilla Netscape' option is checked as well.


Then click OK at the bottom of the Java Control Panel window and close all of your browser windows.


Now open up your browser, go back to Pogo, and try to play again.

I've been asked to submit a Java log. How do I do that?





For Sun Java users:


If you are using the latest version of Sun Java to play our games, you will see a Sun Java icon that looks like a Coffee Cup in your System Tray (near your computer's clock) after you have started loading a game. Right-click that icon and choose 'Open Console'. Then, click the 'Copy' button. Next, go to your response field of your incident, right-click and choose 'Paste', or press CTRL+V on your keyboard.





If you do not see this icon in your system tray near your clock, then you either do not have the latest version of Java, or you disabled the icon from appearing. To enable the icon again, simply go to your Control Panel, click 'Java', then on the Advanced tab, click the plus sign (+) next to 'Miscellaneous' and check the box next to "Place Java icon in system tray". Then, click OK and start over with the first paragraph to provide us with your Java log.





For MS Java users (Please note that we strongly recommend switching to Sun Java ):


Note: If you're using AOL, you'll need to open Internet Explorer (or right-click the Internet Explorer icon on your Desktop) to view these options:





Go to the Tools menu in Internet Explorer and choose Internet Options.


Click the Advanced tab and make sure you have the following settings:


Browsing


Disable script debugging - OFF


Java VM


Java console enabled (requires restart) - ON


Java JIT compiler enabled - OFF


Java logging enabled - ON


Click the Security tab and make sure the "Security level for this zone" is set to Medium.


Restart your computer for the changes to take effect.





Now your Java Logging is enabled. So the next time the error or problem occurs, you can go to the View menu and choose Java Console. Just copy (hold down the Ctrl key and press the "C" key once) the text in that window and paste (hold down the Ctrl key and press the "V " key once) it into the Contact Us form on our Games Support site to send it to us.





If you're having trouble copying and pasting, check in the C:\WINDOWS\JAVA folder for a file called 'javalog.txt '. You can also send us the contents of that.





If you have any questions, please reply to the request and let the agent who requested it know.





How can I view (or send in) my Java version information?





To find which Java you are using, please do the following:


Click this link to open the Java Version Info window. This is hosted at Pogo.com.


This will make a new in window appear. The window will display information about your Java version that you can use to troubleshoot your issue.





If you want to send this to a Support Agent or have been asked to, please follow the steps below.


Highlight all 3 lines of text in the box of the new window.


To highlight the text, click before the first letter and continue to hold the mouse button down. Drag the cursor to the last character of the third line, and then you can let go of the mouse button.


Copy the text.


To copy the text, hold down the Ctrl key and press the "C" key once. (For Mac users: hold down the Apple key and press the "C " key once.)


Paste the text into the Response Field or the Question Field.


To paste the text, go the text field where you would like the text to appear and left click once in that area. Then, hold down the Ctrl key and press the "V " key once. The text should then appear in the text field.

How can you parse a char to int in java?

I need to convert a char in java to an int... how can this be done?

How can you parse a char to int in java?
Let us start with the parse bit first


http://java.sun.com/javase/6/docs/api/ja...





So you require a string. How do you convert a char to string?


Well take a look at the Character class and you will find this.


http://java.sun.com/javase/6/docs/api/ja...





So to convert a char to a string you use


Character.toString(charData)





Now put that with the parse and you are done.
Reply:i think the easiest way is this:





char c = '9'


int i = Character.getNumericValue(c)





// prints out 9


System.out.println(i);
Reply:Assume that you have a character variable call "c", you can use the command:


int number = Character.digit(c,10);


DONE!

Does anyone consider JavaScript a good web-programming language to learn?What is difference from Java?

I am designing a web page that allows people to make virtual homemade computers and compare its performance and price with that of a pre-assembled store-bought computer they choose, then order the hardware/software they need to assemble the computer in one unassembled package. I wanted to create the web program for this using JavaScript, but I want to know the difference between that and Java, which one would be easier for other computers to interpret, which best fits the situation, and which is easier to learn.

Does anyone consider JavaScript a good web-programming language to learn?What is difference from Java?
JavaScript is definitely a good language to use (and therefore, to learn) for client-side web applications, and if one prefers, in server-side ASP. No offence to Java fans, JavaScript is more suitable for client-side applications because it is faster, and it is less likely that JavaScript is disabled by browsers than the Java applets. Java is a strongly typed C++ - like language whose most widely used application is client-side programming as applets (and as server-side in JSP). JavaScript is also C++ - like to some extent, but is not as strongly typed as Java or C++. JavaScript is a solution for writing event-handlers for form input components in DHTML which offers faster development and better integration with server-side applications such as PHP, ASP and ASP.NET.





I am not sure if client-side application is enough for what you intending to design. May be server-side applications such as PHP and ASP could do better (while you may still need to use JavaScript in some parts). As I know C# and PHP well, I would use either C# in ASP.Net or PHP for server-side, and not JavaScript as in ASP (or ASP.Net). But it would be your choice to use JavaScript. Good luck.
Reply:There are a lot of similarities between java and javascript because both the languages have been developed by "sun microsystems". Although as far as I think, java is more power full than javascript but java can't interact with internet browser as closely as javascript can. So, If you wanna develop it to work in browser than go for javascript otherwise go for java. I also would like to tell u that learning javascript is just a game if u already know java but initially, learning java is much harder than learning javascript.
Reply:Short answer: you'll want to use JavaScript to add dynamic client-side functionality to your web page (e.g. form validation). JavaScript is very well suited for this purpose. Java on the other hand would be a better choice for handling the server-side functionality (e.g. taking the input of a web-form and interacting with a DB). They are very different languages with different features and purposes which some of the other answers enumerate. You'd be best off investing the time to learn Java, after which learning JavaScript would be straight-forward.
Reply:Hi, Javascript is a client side scripting language created by netscape communication, it's interpreted by the web browser and it's used to create some interaction with the interet user.





You can do your program using javascript and it's simple, but you have to take in consideration several issues: Javascript as i said before is interpreted by your web browser and your program is at the mercy of browser users who may sometimes configure their browsers not to run Javascript!!





Java is an object oriented programming language created by sun microsystems. it's a compiled language and you need a compiler to run it. Sun have introduced Java applets to alow programmers to create small web interactive applications. but like javascript some browsers are configured not to run it.





so the best way to do your program is to use a server side scripting language. a server side scripting language reside on the server hosting your site so the browser has no control over your application: try to look for PHP, ASP, CFML...





once more, many people think that javascript and java are similar!! no they are not and they're not created by the same company.





hope this will help you

How do I make a java rpg save option?

I'm making an rpg in java but I don't know how to make an option that saves the progress. Please be descriptive so I can understand because I am pretty new to Java. Please don't answer saying how another programming language is better.

How do I make a java rpg save option?
A quick and dirty way is to create a "GameState" object that holds all the other necessary objecst, and then save them to a file using serialization (java.io.ObjectOutputStream/ObjectInputS... See the Java Tutorial.





You can also write your GameState object as a JavaBean and use the XML serialization for beans to save to an XML file.





Later, you will probably want to store the information in a more flexible fashion, probably using either an embedded or separate-running RDBMS. Take a look at either Derby (comes with JDK) or HSQLDB.

Why is Java so Dogmnatic about everything being a part of a class?

One of my main complaints about java is that the language insists everything be part of a class including main. However, since main() is called before a class has been instantiated, it must still be static, which is frankly, the same as being a global function!





Can anyone defend the purpose in having main() as part of an uninstantiated class?

Why is Java so Dogmnatic about everything being a part of a class?
I tried googling this for a while and could not find a clear answer (or anything that alluded to a small explanation!).





I really do not like OOP at all. I remember my first Java class- it was also my last.





Not only is the coding obnoxious, but what a memory hog java is! UGH.





Actually Java is the reason I changed my major! LOL no kidding.





Good luck on your quest; I'll be watching this to see what others say.





Come to the Unix side. We're waiting for you. ;)
Reply:How would you prefer to write it? It's never bothered me.





It just simplifies the types of files to maintain to one. A class. And by doing it this way, you can easily add a main method to any class and be able to instantiate it from the command line.





I think the real problem you're having here is that you're trying to write procedural code in an object-oriented language. You really have to embrace the whole oo mentality to enjoy the true beauty of java. If the way you think about solving a problem is by executing a series of steps (procedural), rather than creating a collection of tools (object-oriented) than you're probably using the wrong language.

How can I hide the cmd window in Java?

I'm writing a Java program with a GUI for a course assignment.





I would like to know how I can hide the cmd window so that it doesn't show when running the program, and that it closes automatically when I close the GUI window.





Thanx in advance.

How can I hide the cmd window in Java?
I think you mean the DOS prompt? Because I think most on these boards are Microsofty...





You can Java Web Start


You can launch with a double-click of a jar


You can write a launcher in C


You can write an applet and the applet launches the GUI (see inside your JDK1_6_xx --%26gt;demo --%26gt;jfc --%26gt;Java2D --%26gt; the Java2Demo.html and the companion /src, tracing the first 3 class


You can write a .bat that starts out with: java spiffyGUI


(then, I don't know the commands, but you would minimize DOS prompt, and java puts up a splash screen). The .bat approach does allow a "poor man's" desktop icon. After you create the .bat, you can change it's desktop icon.





Out of those options, the Java Web Start (JNI) is the best option, followed by the jar. Any method to hide a DOS launch puts two taskbar buttons on Mr. Windoze GUI.

Why can't I see the java games I downloaded on my motorola razr?

I downloaded several games for my Razr but the display only shows part of the game - sort of like when the resolution is set too low for a computer monitor. I can't find any settings to adjust the resolution on the phone or the games. Can anyone help? Thanks!

Why can't I see the java games I downloaded on my motorola razr?
Well.... first of all, the RAZR SUCKS. *ahem* sorry. anyways, it depends, did you down loadit off of get it now, or a web site? if you downloaded it off of get it now, your phone may have a problem. if you downloaded it off of a website, the game is not properly formatted for phones.

Is it ok to download the java program that runs runescape?

I wanted to know if it had any viruses because i dont have protection. I know i should but i have not gotten around to buying it yet.

Is it ok to download the java program that runs runescape?
The version of Java that RuneScape uses is made by Sun Microsystems, the company that created and makes all the updates of Java. Sun Microsystems would not put viruses in their updates, since they'd lose way too much money.





Put it this way. Sun Microsystems has been churning out virus-free versions of Java for years. They'd lose a lot of money and trust if a virus showed up in an update.

Windows Vista users do you have trouble running Java on your computer?

I play alot of Pogo games and everytime i try to pull up a game I get a stupid error screen so I go and delete the Java already installed and re install it then it will pull up fine for a few days then bang there it is again !

What are the differences between java script and html links?

How do they related in terms to legacy links? Maintenance? Loading time? Any and everything else?

What are the differences between java script and html links?
HTML is a language that creates all the beautifull colors in a webpage, and it helps you put the objects in place, replace backgrounds.. But Javascript is a small programming languages that can be used in an HTML page, but you can't make Javascript pages, javascript is used to create an active interface like webforms or to solve some internet problems.. It's a small interactive program online if this makes it more clear.





For the loading time well there is no difference since you can't have a javascript page with HTML as the base.
Reply:You can do some interesting things with them, for instance opening the link in a new browser window without a status bar, address bar, buttons, etc.





The only major concern I can think of is that really old browsers just don't support JavaScript at all and won't even parse the scripts, let alone follow the links properly.
Reply:There are only HTML links, anchors.





You might want to rephrase the question.
Reply:If you want to rank good on the search engines stay away form generating links through JavaScript as long as it is possible. JavaScript generated links can be dynamic while HTML links are always static.

What is the function of java vertual and how is it installed?

Is it advantageous to have it installed?

What is the function of java vertual and how is it installed?
Is it advantageous to have it installed?


Yes. You will need it to run java programs in your browser or on your desktop.





What function does it serve?


The Java virtual machine is a bit like a translator. I'll explain.





Most software programs when they are created are written in a human readable code. Then a compiler and linker takes that code and compiles it into machine code. That machine code can only run on very specific hardware and operating systems. Programs Like Microsoft Office are an example. It has to be compiled to run on Windows. To run on a Mac it has to be recompiled use a Mac compiler.





Java programs are different. They aren't compiled into machine code. They are compiled into what's called, "Java Byte Code". When you run a java program, the virtual machine translates the Byte Code into Machine code.





The advantage of java is that you only have to compile and distribute one version of your program. If Microsoft office was created using Java, you would bye only one version of it and it would work on both your Mac, WindowsXP\Vista, or any other operating system that has a java virtual machine on it(Like Unix or Linux or your Mobile Phone). Instead, you have to bye different versions.





The disadvantage of java is that it comes at a price of speed. The virtual machine translator slows down your program. Though the speed keeps getting better with each release.
Reply:It allows you to run java programs in your browser without installing java SDK
Reply:Java Virtual it's a pluging that will run Java aplications on your machine, not necessarily Internet based aplications but is the common use of it.





Most web pages will telll you to download teh Java virtual once you get in there and you don't have it, providing direct links to the download installation package, but you could also go to their main website www.java.com the first thing you'll see it's the download link wich is free.

In Java if you do not explicitly declare accessor type for instance variable what accessor type is assigned?

For example if you have





public class Example{


int someNum;


}





What accessor type is assigned to someNum by the java compiler. Is it public or protected?

In Java if you do not explicitly declare accessor type for instance variable what accessor type is assigned?
If you use the default visiblity it is "package" visibility. Meaning that field or method is visible to other objects and classes in the same java package.
Reply:NetBeans will not let you assign an accesor to instance variables-- after the constructor, and that's logical, only class-definition variables need the degrees of visibility -- defined outside the constructor.





In your example, you have the default visibility accessor... meaning that only a class within that same package can see int someNum. Default and final are the other accessors -- like protected and private.
Reply:That's a good question. I didn't readily find the answer but it would be most logical for them to be private, so that they are only accessible within the class. That would cause the least upset if one forgot to declare an accessor type.
Reply:fields are private by default, but it's good practice to give them a type.

How do you download java games onto Samsung u700?

I live in singapore and i went through this tutorial thing.


But when i enter a code on the main screen, it doesn't let me install MIDlet and stuffs. Is it because of my country?

How do you download java games onto Samsung u700?
Hi there, im from singapore too!





First of all you must be a wap enabled user. Call your service provider to subscribe for it if you havent.





After you are wap enabled and If you wanna download games, go look for "Internet" in ur phone and look for "Bookmarks" and click on "Samsung fun club". Inside you can download lotsa cool stuffs. By the way you WILL be charged accordingly to the price of the games. It cost around a meal. :)





Im not sure about the Code you entered on the main screen. Maybe you can try to reset the phone and try to download again. Last resort you may wanna call up samsung care center and tell them your problem. But you shouldnt mess too much with the Code on the main screen, because some of them will affect the softwares of the phone it self.

Have been trying to play free games online but says i need java enabled or installed?

Have been trying to play free games online but says i need java enabled or installed?
Well, you could try a couple of things.





First thing, I would reinstall it, but this time go to custom install and do a complete installation of everything. After this, I would restart the computer, even if it didn't ask me to.





If this doesn't work, I would try out another browser. You could download Firefox (www.firefox.com), and see if this makes it any better. Internet Explorer tends to get a lot of problems, and firefox is a lot better for the internet in general.





If the browser was the problem, I'd reinstall Internet Explorer, as there may have been some sort of spyware or virus that has caused it to act differently.
