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 installed java several times successfully, thats what the screen says but still unable to launch any free game sites.getting very fustrated with this. our computer uses vista. have been able to play before but as first of year have not been able to get any free game sites to come up.keeps saying there is a problem or mistake.please help .
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.

Reply:Go to your firewall settings and add Java Browser as an exception so that your firewall won't block it anymore.
Reply:I don’t imagine work (corporate) firewall would be able to block any particular browser, therefore assuming you meant „java” script in browser.

How do I grow java moss?
Right now I just have around a nickel sized portion and I'd like to know how I could grow it as fast as possible.
I need to know what is the best situation for it to grow under.
How do I grow java moss?
If you have cool water %26lt;28C, alittle light (not strong sunlight) and CO2 (DIY CO2 is good enough), plus alittle liquid fert for meant for aqautic plants.
Reply:unless you have a 5 watt lightbulb it will most likely grow. and fast. it kind of grows exponentially. the best thing to do is attach it to something and it will grow.
this video has a great idea for a clump of moss about 2/3 of the way through --
http://youtube.com/watch?v=bdbjjWuf8y0
Reply:Add some blackwater extract to your water...gives the traces of humic acid and creates the brackish water that java moss naturally thrives in. Give it a good amount of sunlight, but not direct light. That's about it. You can't really accelerate the growth of java moss by very much, but it does grow pretty fast on its own.

How do I calculate the difference between two calendar dates in Java?
if you are using Date objects, it's as simple as using the getTime() method... as in
Date x y;
...
long difference = x.getTime() - y.getTime();
otherwise, if you are using Calendar objects, the best way is to use the built-in compareTo() method. It takes another calendar object as argument:
Calendar x y;
...
long difference = x.compareTo(y);
either way will get you the difference in milliseconds.
if you need to do more complex comparisons (like w/ days of the week, etc.) then go to the documentation:

How do i read a whole line as a String in Java?
I am trying to implement a code using java that will take in a whole line of inputs as one String. However, the number of inputs is unknown to me. I heard about Scanner and the scanner.nextLine() function but can't seem to implement it well and falls into an infinite loop. Anyone knows how to better implement it or work around it?
How do i read a whole line as a String in Java?
You can use BufferedReader class to read a entire line
The below is a sample program to read a entire line from console...
I have written username you can input a long line ... It will just read the entire line... and assign it to variable username
import java.io.*;
public class ReadString {
public static void main (String[] args) {
// prompt the user to enter their name
System.out.print("Enter your name: ");
// open up standard input
BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
String userName = null;
// read the username from the command-line; need to use try/catch with the
// readLine() method
try {
userName = br.readLine();
} catch (IOException ioe) {
System.out.println("IO error trying to read your name!");
System.exit(1);
}
System.out.println("Thanks for the name, " + userName);
}
} // end of ReadString class

How do i keep from getting booted out of a java game lobby?
never had that happen! yahoo usually blocks script codes.Try using MSN vm instead of sun java.
Yahoo games, mail, and messenger, have conflicts with sun java. Rather then trying to work around them. Here is the easy and fastest way to cure them. These simple setting changes will fix 90% of all problems caused by java updates. While you need java for most yahoo sites, you do not need sun java’s virtual machine to launch them.
You can set default here! ... click start / settings / control panel
Now open the add / remove programs folder
Click on set program access and defaults
Choose Microsoft's Virtual Machine java ... NOT... Sun java.
Increasing your virtual memory helps with the freezing/getting booted problem. You can increase your memory by going to start button, settings, control panel, system, advance tab, performance, advance tab, virtual memory, change it, make it 900 kb or higher, click set then ok

How to shrink java project to get rid of unused classes and packages?
I use open source application, by defining the jar as a classpath. In in my main class I use only one feature from a number of others the open source application provides. I tried to determine the classes and got mixed in the huge amount of classes and packages. Tried obfuscators but got error messages. Has anyone experienced such issue before and how resolved. Does Eclipse or Jbuilder provide any serious tool for that except viewing class trees, etc.? Thanks
How to shrink java project to get rid of unused classes and packages?
Well, there is a very old project call JARG (see URL below) that apparently has this capability.
The one thing to note though: Java code can dynamically generate strings and execute them. That means that there is no way for any tool to be 100% sure ahead of time what classes will be needed at runtime (for example, my code could ask the user to enter a classname and a method, which the program could then load and invoke).

You don't need code just call the page index.html
and it will be the default page to open at the address.

How do I get up and running to program in Java?
I'm a .net programmer using Visual Studio I'm familar with J# never programmed it but I want to code in just good old Java. I"ve taken courses but anyone know how I setup a complier to do so I've attempted to it's not an easy setup like visual studio. It, was all CLI and I ended up not even get it working.
How do I get up and running to program in Java?
If you want a visual-studio-like environment, go to java.sun.com to get JavaSE (Standard Edition) as outlined by others here. After installing it, go to www.eclipse.org and download/install the latest version of Eclipse.
Eclipse is a free shareware development environment brought to you by your friends at IBM. It is very robust and has an almost limitless number of plugins that can be found for free and for purchase out on them there internets.
There is a tutorial on the eclipse website and the equivalent of a tutorial in the help docs, but even without that you should not have to look to hard to find your favorite MSVS development features.
Give it a whirl.
CAVEAT DOWNLOADOR: Eclipse is not the only free dev environment for Java, and there are some who would say it is not the best dev environment for Java. However, most Java developers would probably agree (some grudgingly) that Eclipse is the best free development environment for Java.

too bad it won't be that simple when you first try it ;-)
If you are use to VS, then download any number of Java IDEs. NetBeans is fairly simple and free.
However, if you are already doing .NET programming, just switch to C#. There are a lot of things about Java you are going to hate compared to C#. C# fixes a lot of Java's shortcomings. Java JUST got enumerations but still does not have accessors, structs, pointers. And don't get me started on exception handling in Java - what a hack job.

How to set the text file size dynamically from java code while writing to a file using OubjectOutputStream?
I have written some contents into a text file ie to a notepad in java. How can i set size for that file? That is I have to remove the empty space in the notepad after i wrote the contents in it. Bec while printing that text file using dot matrix printer the paper is scrolling till the end of the file. The printer should stop after it reach the end of file. It shoud not scroll the empty paper. Plz help me..
How to set the text file size dynamically from java code while writing to a file using OubjectOutputStream?
A text file normaly contains an end-of-file marker at the point at which the file ends.
When you open this file using any text editor (say - notepad) - this character is not viewable.
Now when you print this file - this end-of-file character is send to the printer, which when sensing the same generate a form-feed which will cause the printer to scroll to the next page.
Also in dot matrix you can define paper-size

I have a Java fern and was wondering?
I own two java ferns and they seem to be growing roots and leaves off of the regular leaves, can you tell me if the new roots and leaves will fall off on their own or do I have to pick them off and replant them into the gravel in my tank.
I have a Java fern and was wondering?
Just bend the leaf over and put a piece or two of gravel on it. The new little plants will detach themselves in a few days to a week. Or if you like you can cut off the leaf and cut each little new plant away from the leaf. It's better to allow them to detach by themselves, but this can work too.

Reply:The new growth is a daughter plant. It will grow attached to the leaves of the mother plant until it is ready to be rooted itself at which point it will release and drift off. If you wish, you can replant the daughter plant, but I would wait until it releases itself.

I need to make a better cup of coffee. How do I make rocking java in my Krups?
Mojo points out I should probably make it at home. I need to save money and the aggrivation of the snooty Barista's. How do I make it just as yummy? My house guests will appreciate your help.
I need to make a better cup of coffee. How do I make rocking java in my Krups?
Store opened or bulk coffee in an airtight, opaque container and store at room temperature for up to a week (never freeze beans).
Grind coffee as close to brewing time as possible. For drip method, grind in blade style grinder for 15 to 20 seconds. For French presses, grind for only 10 to 12 seconds.
Regardless of method, brew using 2 heaping tablespoons of coffee for each 6 ounces of clean (filtered or bottled), cool water. If you prefer a milder cup, brew to full strength, and then dilute with hot water. Brewing with too little coffee will result in over-extraction, and that means bitterness.
If you really want to taste the subtle nuances of regional coffees, consider a gold mesh filter heating water to 185 degrees.
When purchasing a coffee maker (either manual or electric), look for a model that brews into a thermal carafe rather than a glass pot designed to sit on a heating element. Continuous heating of coffee leads to bitterness.
Reply:Go with Mojo on this! He completely nailed that answer, if he wouldn't of said it, I would've. Spot on answer.
I would like to point out that donuts are a wonderful accoutrement.
Reply:(1) Hotter
Warm everything up beforehand so that nothing chills the brew.
(2) Stronger
Put so much in that you're pretty sure you're overdoing it
(3) Longer
Don't rush it; keep it warm and wait till the aroma hits, then serve it up and enjoy.
Reply:I guess this Krups is an automatic coffee maker? Then be sure that the coffee you get is ground for that type, #1.
Then buy good coffee - not the less expensive stuff like Folger's and Maxwell House. You cannot have great coffee without great beans.
Then you'll have to experiment with how much ground coffee per amount of water you consider a "cup." Usually, it is a rounded tablespoon per 6 oz of water, as a basic start.
Then, make sure you make it with good water and start the water cold.
You have no choice of brewing temperature with automatic coffee makers, but that's ok, because the water going into the grounds is not boiling. Good coffee is not made with boiling water - it should be 190 degrees F.
Good cuppa coffee = good coffee grounds in a good amount made with good water at a good temperature.
Reply:blah
Reply:Make it strong. Use lots of grounds and COLD water to pour through the coffee pot!! And buy Folgers "Gourmet Supreme" coffee grounds instead of classic crap.

Calculating the difference between two times in java?
hi, i'v got two times and i want to caculate the differernce between them. they are both Strings so will i have to convert them into milliseconds first or is there a way to do the calculation directly?
Calculating the difference between two times in java?
Here I was thinking that you were asking about two different times on the island of Java, in the Republic of Indonesia. Based on a time zone map, the entire island is in the same time zone, same as Christmas Island, Vietnam, Laos, Cambodia, and Thailand.
http://upload.wikimedia.org/wikipedia/co...
But based on your further description, it seems that you are calculating times within the java computer programming language. That's completely different... I'd probably start with the Java tutorials: http://java.sun.com/
Reply:First you have to do parseInt to get it into an integer and then do the calculation. You can never do a calculation when the number is stored as a string.
Reply:It might not be easiest way, but I'd splint the Strings into integers, create GregorianCalendar objects, convert to longs (milliseconds), and then subtract. Then you've got a bunch of % operations to get back into sensible times.

In java, How can I display the contents of a text file in a textarea using the open dialog box?
Using swing components I created a text area and a butten named 'open'. When I click the 'open' button an opendialog box should appear and thus I can select a text file. How can I display the contents of the file into the text area? Can it be done only with the concept of files only? If you know please wite the source code.
In java, How can I display the contents of a text file in a textarea using the open dialog box?
Using the opendialog box will return the name and path of the file, then use it accordingly. PS I've not checked this code works so there may be the odd typo in here.
String allText = "";
String filePath = "c:/folder/file.txt";
BufferedReader r = new BufferedReader( new FileReader( filePath ) );
String line = r.readLine();
while ( line!=null ) {
allText += line;
line = r.readLine();
}
r.close();
yourTextArea.setText( allText );
This should get you along the right tracks
Reply:Look up JFileChooser and limit the selection to files instead of directories. You will find more information if you google about Jfilechooser. You can used buffered reader or something similar to read the text and use the set Text in text area to the text read by the reader.

How to keep the aspect ratio on a Java GUI window?
I'm coding up a GUI in java using swing and java2D and would like all the components within the window to expand or shrink down in relation to the size of the window. What's the best way to do this?
How to keep the aspect ratio on a Java GUI window?
Use an appropriate Layout such as GridBagLayout or SpringLayout
example:
Container contentPane = jframe.getContentPane();
contentPane.setLayout ( new GridBagLayout() );
// x y w h wtx wty anchor fill T L B R padx pady
contentPane.add( myPanel, new GridBagConstraints( 0, 0, 1, 1, 0.0, 0.0, GridBagConstraints.WEST, GridBagConstraints.BOTH, new Insets( 10, 10, 10, 5 ), 0, 0 ) );
contentPane.add( myPanel2, new GridBagConstraints( 1, 0, 1, 1, 0.0, 0.0, GridBagConstraints.EAST, GridBagConstraints.BOTH, new Insets( 10, 5, 10, 10 ), 0, 0 ) );
I just read your additional note. You also would like labels, etc. to be expanded as well. Hmm, I don't know of anything that will do this automagically for you. You could extend some of the components to take hints from the layout and resize appropriately. For instance, you may choose to enlarge the font when you determine more whitespace is available due to a window resize. I'm not aware of existing component that will do this for labels. Proportional fonts are a bit tricky to get this right. Actually, if memory serves me, I once did something similar. It was like "trial-and-error" programmatically. Off screen, I would draw the character string in the estimated font size and redraw down until it fit in the allotted space with the desired margins. Sure seems like a lot of trouble to get these dynamic labels to look good!
How to keep the aspect ratio on a Java GUI window?
Use an appropriate Layout such as GridBagLayout or SpringLayout
example:
Container contentPane = jframe.getContentPane();
contentPane.setLayout ( new GridBagLayout() );
// x y w h wtx wty anchor fill T L B R padx pady
contentPane.add( myPanel, new GridBagConstraints( 0, 0, 1, 1, 0.0, 0.0, GridBagConstraints.WEST, GridBagConstraints.BOTH, new Insets( 10, 10, 10, 5 ), 0, 0 ) );
contentPane.add( myPanel2, new GridBagConstraints( 1, 0, 1, 1, 0.0, 0.0, GridBagConstraints.EAST, GridBagConstraints.BOTH, new Insets( 10, 5, 10, 10 ), 0, 0 ) );
I just read your additional note. You also would like labels, etc. to be expanded as well. Hmm, I don't know of anything that will do this automagically for you. You could extend some of the components to take hints from the layout and resize appropriately. For instance, you may choose to enlarge the font when you determine more whitespace is available due to a window resize. I'm not aware of existing component that will do this for labels.

Where can I buy loca moca java energy drinks in bulk?
I have found the drink 24 pk for 57.00 + 9.00 shipping.. Does anyone know where to find a coupon?
Where can I buy loca moca java energy drinks in bulk?
Wow. That's more expensive then they are in the stores.
Wait until they go on sale at your local grocery store. Then, ask them to special order a full case for you. Buy the full case at the sale price. Java monster is on sale at one of our local chains right now. Stocking up when they're on sale will still be expensive, but $40 a case is WAY better then the $66 you'd be paying. You could get a case at regular shelf price for less then that.
Reply:I would like to know the same thing. Thanks

What causes Java Script to become disabled?
Every once in awhile I get a message on my computer screen stating my Java Script has been disabled. I have changed nothing. I log out and sign back on and it is back to normal. Why is this happening? No one apparently seems to know why it is happening cause I have asked this question 3 times now and have not received any answers.
What causes Java Script to become disabled?
It's because no one know. Need more info like what kind of OS you're running, anti-virus? firewall ? browsers?......etc..My guess is that one of the security software on your PC is doing it. You need to find out which one. Check your browser Java settings everytime you use it or startup your PC to see if it's changed. You also want to download the latest version of Java since the newer version may not have this problem. I believe that the latest Java is Version 5 Update 10.
Reply:Ted was right on the part that you need to give information about OS, browser etc. Though Javascript != Java, hence if javascript is not working on your browser then it could be possibly due to the fact that javascript has been disabled in your browser. Unless you give more information it is difficult to figure out what could be the problem.
In Internet explorer, you can find the setting at Tools%26gt;Options%26gt;advanced. Or you just click on "restore default"
and then restart the browser, and see if that helps

What are differences and comparisons of HTML and Java programming?
Hi,
I was wondering if you could possibly tell me some similarities and differences between HTML and Java programming?
Thanks for your help!!
What are differences and comparisons of HTML and Java programming?
To be honest, there are very few similarities between HTML and Java.
HTML is what they call a "markup" language, and is an "interpreted" language, not a compiled one like Java. Basically, all HTML does is define the appearance and layout for webpages. When a page is loaded, the browser "reads" the HTML for the page, and it tells it where to put the various elements, what colors to make them, etc. It is not capable of performing any kind of logical checks, calculations, or data manipulation - it just defines appearance.
Java, on the other hand, is a full blown, 3rd generation programming language, capable of performing sophisiticated data manipulations and calculations. Java is a compiled language, meaning that before a Java program can be run or redistributed, it must be "compiled", which basically turns the code into a language that the computer can more easily understand.
Typically, HTML is used for the "front end", and Java is used for the "middle tier", connecting to a database at the "backend". Hope this helps a little.
Reply:HTML and java are completely different.
HTML is a markup language .. i.e. it just defines how the data must be represented which should not be confused with a programming language. You cant program any logic.
whereas Java is a programming language where you can actually provide some type of logic.
Reply:Other than both of them being object oriented programming languages, they barely have anything common.
Differences that come into mind first:
1. HTML is strictly front end language, Java is not
2. HTML is a script - it gets compiled/parsed on the fly by the browser while Java is pre-compiled into bytecode prior to become usable
3. HTML is only usable within a browser, and can barely do anything other than displaying info passed to it while Java is capabale of data processing of virtually any complexity.
4. Pretty much everything else...

How do I transfer a java game that I have on my PC to my mobile?
It depends on your service provider. You cant transfer it by cable (normally). If you do NOT have Cingular, then you can do so using a special program. Send me a message for the website info for it. If you DO have Cingular, then its a 50/50 shot that the program will work once installed on there. It all depends on the version of software and how old the phone actually is. Send me a message. I will try to help out.
Reply:You cant transfer a game runnable on your pc to your mobile.
java app on your pc run on top of a JVM (not for running midlet)
java app on your mobile run on top of a KVM (support a kind of java app which is called midlet.
However, if you have written some java midlet (or downloaded some java midlet) which is runnable on the mobile emulator on ur pc, you may try download it to your mobile using bluetooth service.

How can I cast a String variable value into a double variable in Java Programming?
I spent all day to figure this out %26amp; I get an error when trying to compile. I am trying to write a code using Java Programming. The code bascially gets a value from the user and does some calculation and prints out the result. The value that I get from the user should be String and I should cast it into double variable, how do I do this? Thanks a bunch!!
How can I cast a String variable value into a double variable in Java Programming?
hello, for java programmers it is very much easy. u r also trying to become a good java programmer. keep it up.
consider the following code segment.
double dTot;
String s = "11316500.00"
double dTot=Double.parseDouble(s);
in this way you can convert the string to the double variable.
Note: you can convert the double basic data type to the object as
Double dObj = new Double(s);
this can be used at the situation when you want to convert the double value to the object.

Reply:Try using a Double object with the method
static Double parseDouble (String s)
with s being the string you wish to convert

Alternatively, you can simply obtain Sun's JDK for command line work; this will have the smallest footprint but very limited debugging tools.
If you desire J2EE application server development, you might consider Apache Geronimo or JBOSS app servers.

How does one become a java devloper? What courses should I look into and what certification should I get?
What is the job function of a java developer?
The "cookie cutter" answer is someone who is able to take business requirements and objectives, and make a meaningful application that is able to solve that particular business problem. The best Java developers will not only take into consideration the actual business problem being solved, but will also create a "framework" of which that problem solving application can be used for a multitude of other business problems. Also, the typical request for java developers is to have a myriad of different skills other than technical; As in, "With a financial services background", or "Help desk background". It's important to understand that Java development %26amp; related technologies in and of itself is not that important. It's being able to apply Java and it's related technologies to best solve unique business problems in the easiest(most of the times "best") way possible. That's a double edged sword. The easiest is quite often not the best. Here's a typical Job posting for a "Java Developer":
7-8 years of solid programming in skills in Java/J2EE, C#, etc. Must have finacial industry experince.
Experience in building enteprise applications in J2EE.
Experience in building enterprise framework integrating varous business processes.
Experience in Web development.
Excellent communication and academic background is a must.
Some basic knowledge of databases required.
Scripting, especially Perl
Basic Linux %26amp; Windows systems administration
As you can see, most employers are not looking for someone who can "code" java. A lot of people can do that. What they are looking for is industry expertise that can help them solve those business problems. Which usually involves not only Java, but C#, perl, %26lt;insert any other language or scriping language here%26gt; and system adminstration duties as well. Please also note the "background" stuff they always seem to ask for. The best way to get a particular "background" is to intern somewhere that will give you experience in an area you find most interesting(this typically will keep you motivated).. Other than that, don't learn only Java. Learn J2EE, learn SQL %26amp; Databases(the big ones are Oracle, DB2, %26amp; MSSQL) learn Java beans(which are related to J2EE), learn XML, and for the love of pete learn to read javadocs! There's a lot of problems that have already been solved in existing java classes that are out there on the internet. Java is to be reused and "should" run anywhere(not too often the case in enterprise software).. A real good place to start is http://java.sun.com This is pretty much just a brain dump on my part. I hope this helped.

How to set significant figures in Java Programming language?
I'm writing a simple ATM machine for my java programming class. I currently have it all set to work and my only problem is that when there is no change to be displayed. EX 100.00, is displayed as 100.0, or One dollar is displayed as 1.0. How can I set it to display currectly like a true ATM machine would do with both decimal places. Thanks for you help
How to set significant figures in Java Programming language?
Java 1.5 offers a printf-like formatting via java.util.Formatter or via the 'printf' method of an output stream:
e.g.: System.out.printf("%.2f", (double)100); or
String output = String.format("%.2f", (double)100);
Reply:The answer you are looking for is the printing. You select how many decimals there are at the print stage. Look at the DecimalFormat class for the secrets.
However this is NEVER done in the real world. You'd use something like BCD or integer arithmetic to ensure that you have no awkward decimal fractions to deal with.

You say cage... and someone else say its ok in an AVIARY. How much space do you have ? If its just a cage I would say NO. We had Javas in an aviary 10 metres by 3 metres by 3 metres with other finches, canaries and parrots. The Javas ( although very pretty ) were so active and annoying to all the other birds we had to sell them. AND our aviary was HUGE !! I would say NO.

How do I create a Java bean for Drop down menu and call the bean in Jsp!?
in the java bean:
u need to create the element as an array, and fill up the elements.
Have getter and setter for the element
in the jsp, u can just call the array and loop it and display the elements in the array.

How to check whether a file is opened or not through java?
Here is the situation:
My java code needs to check that a file is opened or not in time of execution.Let I have opened a text file(aaa.txt) from windows and then I want to give a confirmation through my code something like(the file is opened). please help with just the code for check this condition.
How to check whether a file is opened or not through java?
I don't think you can do that. When you ask java to open the file it can read from it. If you don't open the file in the code, the Java wont see the file at all. You might want to look at the swing libraries, they might have some file manipulation there. Also, make sure that the file you are opening in the directory where the java can read it. Meaning if it in the same place as the code or the total path of the file.
Reply:If your file is already open then the canWrite() function will return false
so your code can be
if(file.canWrite())
{
//Do what ever you want
}
else
{
file.close();
}

How can I add Java Script to my desktop?
I down loaded Java Script all the way to the point of "Finish" and it said "successfully downloaded", yet every time I try to access it, I have to go through the web to get it. If it was successfully downloaded and appears on my programs menu, how can I access it from my desktop? I want to make it an icon on my desktop for easy access without having to go to the www.
How can I add Java Script to my desktop?
Java Script is a script, it is text, a javascript file would be a text file. You would open it in notepad. It cannot do anything by itself, it has to be interpreted by a host, which for javascript is usually a web browser. Your description makes me think it is not javascript, but rather a java program which you are trying to run. What exactly are you trying to get (you can email me, it's in my profile)?

On a java enabled moboile phone is it possible to get a virus, when downloading games etc?
Also if it is possible what is the worst the virius could do?
On a java enabled moboile phone is it possible to get a virus, when downloading games etc?
Unfortunately Java-enabled devices are not exempted from viruses. So to answer your question, yes it is possible to get them from downloading games, java mobile apps, etc.
The worst it can do? Well whatever a computer virus can do to your computer (wipe out files, wipe out OS, etc.), may also happen to a mobile phone struck with virus. So the only way to avoid this is to make sure you're getting the games/apps from reputable sources (like perhaps an extra service provided by your mobile network).
Reply:Yes, many viruses have %26amp; can be downloaded to phones. the range of problems that can be caused depends on the specific virus just like with a pc etc

What is the best substrate that supports java moss?
I have a 16 gallon tank with a pair of breeding kribensis.
What is the best substrate that supports java moss?
Wood, by far.
Use wood from an aquarium supply store to avoid adding other nasties to your tank. You can attach the moss with a rubber band or two at first. These can later be cut off when your moss has attached.
The tannins from the wood will be beneficial for your kribs, too.
Reply:Java Moss does not need substrate. I dropped a bunch in a bare tank where I had some swordtails and in about a year, they grew until they covered the entire floor space of a 5x2x2 foot tank about 10cm thick!
If you have a strong filter, the most common material would be a piece of driftwood. I don;t like driftwood because most of the time, they stain the color of the water. I prefer some flat rocks.
Reply:What isnt'! it's fast growing and will attach it's self to ANYTHING! I personally would use a nice piece of driftwood. so if it does get outta control you can give it a hair cut so to speak. Otherwise, something different hang it from a little chunk of natural corkbark, so that it hangs down like Spanish Moss. This plant is only stopped by your imagination.

Is it possible to learn Java thru online? What is the basic knowledge required to learn java?
Please suggest some websites to learn java thru online, preferably free.
Is it possible to learn Java thru online? What is the basic knowledge required to learn java?
Yes,its possible to learn java online.You have an advantage if you already know C/C++ or VB.Net .
Try starting with an IDE(Integrated
Development Environment) , it simplifies the design process for you . The best IDE recommended by Sun themselves is
NetBeans (at netbeans.org) . You can also do mobile programming with NetBeans(you need to download a mobile ext pack seperately).
But before all that you have to download JDK 1.5 upgrade 6.Thats the core , you can write programs without an IDE
but not without the core
Don't follow the herd by taking Sun's own tutorial , its outdated and doesn't support IDEs .Just google for "Java Tutorials thru NetBeans" and many good ones will spring up.
I learnt java through trial and error, because of my experience in C++ and VB . Now I am a programming expert

Is the Java Programmer Certification enough for a job?
I am ready to take the SCJP 6.0 exam. Now since I have no degree. Will I be able to find even an entry level job doing Java Programming?
Or am I just wasting my time reading 2 books to get certified to retrain myself on this stuff?
Is the Java Programmer Certification enough for a job?
It really depends on the specific job you're applying for. Check to see what they require. Entry level typically means *no experience* and are found typically with the minimum of a degree of some sort.
That said, the SCJP is no doubt a good exam to be attempting- it's one of the toughest out there and will no doubt get tougher should you decide to go up the Sun ladder of certifications. It's a highly respected exam and will definitely be an asset on your resume.
However, between someone with a degree(but no SCJP) and someone with no degree(but has a SCJP), the recruiter is likely to consider the person with the degree first.
Certifications are meant to make you stand out amongst the applicants. It's usually not the deciding the factor but it definitely helps- if it's enough to get you the interview, you will then be in charge of aceing the interview. What they're good for, as mentioned, is say between two applicants that have degrees- but only one has a certification, the person with the certification(all other things being equal), will usually be considered first. It's definitely *not* a waste of time though- provided you pass it. :) You just may find a shop that will take you regardless of any degree.
Hope this helps. Good luck!

How do i program convincing jumps in a fighting game I will make as java applet?
I dont' know much about physics..and i don't want to spend a whole lot trying to figure it out. A few years ago i managed to program a whole java game, fighting game i created. It was fun but jumps were kind of cheap.
How do i program convincing jumps in a fighting game I will make as java applet?
I was going to say use Newton's gravitational constant, but since you don't want to do that, I'd say simply make the jump slow down progressively until the jumper reaches the top height, and then do the reverse for the descent.
If you saw the movie Ice Age, there's a scene where this piece of ice pops out of the top of a giant cliff wall. It starts out real slow and then accelerates. Very realistic looking.
Reply:What kind of game is it? Which way u want to put jumps?
I have also made PLANE FIGHTING game: see "aakash.freehostia.com"
If yours is similar, I can answer ANY OF your question, if it's different, please specify how you want to put jumps!

JAVA QUESTION: How are static fields and methods different from non-static fields and methods?
How are static fields and methods different from non-static fields and methods? What would go wrong if we declared the balance field of a bank account class to be static? What could go wrong if every account had a field containing today's interest rate?
JAVA QUESTION: How are static fields and methods different from non-static fields and methods?
Static fields and methods belong to the class not the individual instances of the class. All instances of a given class share the same static variables/methods.
For example:
public class Dog {
public static String breed;
public String name;
}
-----
public class StaticTest {
public static void main(String[] args) {
Dog dog1 = new Dog();
dog1.name = "Spot";
dog1.breed = "German Shepherd";
Dog dog2 = new Dog();
dog2.name = "Fido";
dog2.breed= "Mutt";
System.out.println(dog1.name + " is a " + dog1.breed);
System.out.println(dog2.name + " is a " + dog2.breed);
}
}
When run, you'll get:
Spot is a Mutt
Fido is a Mutt
Because while name belongs to each individual instance of Dog, breed is shared among all Dog's
Hopefully you can see the disastrous results of making checking account balance a static attribute. Everyone at the bank would always have the same amount of money.
On the other hand, keeping today's interest rate in each account is too much overhead since the interest rate should be shared by all customers.
Static methods also work well for functions that don't necessarily require an object to be created in order to run that function.
For example:
public static long farenheitToCelcius(int F, int C);
and
public static final String RGB_BLUE = "#0000FF";
could be called from anywhere without have to instantiate their parent objects.

At what age does a java finch head becomes totally black?
My 7 month old has black lines on each side of it's head, but it's been like that for 4 months. The rest is still white.
At what age does a java finch head becomes totally black?
at this age it is probably going to stay that color. It may change when it molts for the first time next year. But for now it sounds like the color is there to stay.

4)or can we reffer alot to created examples which writing our dossier?
Is it possible to remember all the java codes?
I don't know if the certified Sun developers know all the packages but they sure know the core JFC and it's heirarchy. I've watched them call up methods that were way up the hierarchy without even thinking. As for me, I've grown very dependent on the NetBeans IDE. It uses the javadocs to suggest every possible method Object.method(); with a popup. I always have the API javadocs running as a bookmarked url in my browser. I know the tutorials by heart.
Of couse, I'm self-taught. I've only worked as a contractor coming in to fix things after someone else. Talk about spaghetti code!

You need to use JNI (Java native interface). JNI is difficult to use and very unfriendly. From what I can find, you cannot just call an arbitrary DLL, its needs to have been written with JNI in mind. So unless you have the source to your dll, you won't be able to do it. And if you DO have the source, you will be much better off rewriting it in java. Nevertheless, here is a quick introduction to JNI:

Reply:Use : System.loadLibrary(String) and System.load(String)
if using System.loadLibrary just specify is the name of the DLL file you want. The JVM will search for it in the "Java library path."
and if using System.load , just insert code like:
System.load("c:/path/to/dll/yourdll.dl...

How do I calculate the difference between two calendar dates in Java?
It must be done manually without using date or calendar methods. Or where can I obtain the source code that forms those methods?

You don't need the source code (since you can't modify the variables in the object so it won't do you much good). All you need is the interface which is available on the sun website. I've linked to it in the sources. Good luck.
