How would you position a button in an applet using Java?

Basically, Im trying to make something similar to a calculator with a screen and keypad below it.

How would you position a button in an applet using Java?
The code for positioning a button in ur page is like...


keysArray = new Button[17];


(where 17 is the specified-width, okay?)


Better I'm giving u the whole code for calculator (using Applet), so that u can get the whole points of view...





import java.awt.*;


import java.awt.event.*;


import java.applet.*;





public class CalculatorApplet extends Applet implements ActionListener


{


private Button keysArray[];


private Panel keyPad;


private TextField lcdField;


private double result;


private boolean first;


private boolean foundKey;


static boolean clearText;


private int prevOperator;





public void init()


{


lcdField = new TextField(20);


keyPad = new Panel ();


keysArray = new Button[17];


result = 0.0;


prevOperator = 0;


first = true;


clearText = true;





//Set frame layout manager setLayout(new BorderLayout());





lcdField.setEditable(false);





//Create buttons


for (int i = 0; i %26lt;=9; i++)


keysArray[i] = new Button(String.valueOf(i));


keysArray[10] = new Button("/");


keysArray[11] = new Button("*");


keysArray[12] = new Button("-");


keysArray[13] = new Button("+");


keysArray[14] = new Button("=");


keysArray[15] = new Button(".");


keysArray[16] = new Button("CLR");





//Set panel layout manager


keyPad.setLayout(new GridLayout (4,4));





//Add button to keyPad panel


for (int i = 7; i %26lt;=10; i++) //adds Button 7,8,9, and divide to Panel


keyPad.add(keysArray[i]);





for (int i = 4; i %26lt;6; i++) //adds buttons 4,5,6 to Panel


keyPad.add(keysArray[i]);





keyPad.add(keysArray[11]); //adds multiply button to Panel





for (int i = 1; i %26lt;= 3;i++) //adds buttons 1,2 and 3 to Panel


keyPad.add(keysArray[i]);





keyPad.add(keysArray[12]);//adds minus button to Panel





keyPad.add(keysArray[0]); //adds 0 key to Panel





for (int i = 15; i %26gt;=13; i--)


keyPad.add(keysArray[i]); //adds decimal point, equal, and addition keys Panel





add(lcdField, BorderLayout.NORTH); //adds text field to top of Frame


add(keyPad, BorderLayout.CENTER); //adds Panel to center of Frame


add(keysArray[16], BorderLayout.EAST); //adds Clear key to right side of applet





for(int i = 0; i %26lt; keysArray.length; i++)


keysArray[i].addActionListener(this);


}
