if you are using threads:

Code:

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

public class TimerTest extends Applet implements Runnable
{
    final Thread timer;
    
    final int cycletime = 1000;
    
    public void init() {
        setSize(500,500);
        timer = new Thread(this);
        timer.start();
    }
    
    public void run() {
        while (true) {
        
        
            // Do things here
            
            
            try {
                timer.sleep(cycletime);
            }
            catch (InterruptedException ie) {
                System.out.println("ERROR sleeping");
            }
        }
    }
}

I prefer Threads, they're easier.

to stop the above Thread: timer.stop() (deprecated) or timer = null
