hi all,

how can we add multi-threading to Applets..??
A single thread can be created like..

class MyApplet extends Applet implements runnable{
Thread t;

public void run(){

}

public void start(){

}

public void init(){

}
.....
........

}

but, can we have 2 threads in a single Applet ??

import java.applet.*;
import java.awt.*;
import java.io.*;
import java.net.*;

public class test1 extends Applet implements Runnable {
     volatile Thread t1,t2;
     volatile int i,j;

     public void init() {
         t1 = new Thread(this);
         t1.start();
         t2 = new Thread(this);
         t2.start();
     }

     public void run() {
         while (true) {
             try {
                 if (Thread.currentThread() == t1) {
                     i++;
                     Thread.sleep(50);
                 }
                 if (Thread.currentThread() == t2) {
                     j += 2;
                     Thread.sleep(100);
                 }
             } catch (InterruptedException ie) { }
             repaint();
         }
     }

     public void paint(Graphics g) {
         g.drawString(Integer.toString(i),20,20);
         g.drawString(Integer.toString(j),20,40);
     }
}
