 public class Clock extends Applet implements Runnable{
        Thread clockThread;
        public void start(){
               if(clockThread==null){
                      clockThread=new Thread(this,"Clock");
                      clockThread.start();
               }
        }
        public void run(){
               while(clockThread !=null){
                      repaint();
                      try{
                             clockThread.sleep(1000);
                      }catch(InterruptedException e){}
                   }
        }
        public void paint(Graphics g){
               Date now=new Date();
               g.drawString(now.getHours()+";"+now.getMinutes()+";"+now.getSeconds(),5,10);
        }
        public void stop(){
               clockThread.stop();
               clockThread=null;
        }
