         System.out.println(counter++);
      }
      if (stop)
      System.out.println("Detected stop"); 
   }
   public void requestStop() {
      stop = true;
   }
}
public class Stopping {
   public static void main(String[] args) {
      final CanStop stoppable = new CanStop();
      stoppable.start();
      new Timer(true).schedule(new TimerTask() {
         public void run() {
            System.out.println("Requesting stop");
