Where Can I Learn To Make Java Applets ? - Where can I learn to make java applets ?

CODE

import java.awt.*;
import java.applet.Applet;

public class Example extends Applet
{
   
    public void paint(Graphics page)
    {
         //code for creating graphics go here
    }
    //any additional methods or code go here
}

CODE

<APPLET CODE="Example.class" WIDTH=500 HEIGHT=500></APPLET>

"WIDTH=500" sets the width of the functioning area for the applet
"HEIGHT=500" does the same thing for the height
"APPLET CODE="Example.class" tells the brower to use the code in the class file Example.class to run the applet once it is open

// This applet draws an animated bouncing ball with uniform speed.
// The ball starts at the center of the graphics page and bounces off
// the top and bottom.
