The task can check when - * it should have been scheduled and cancel itself when no longer needed. - *

- * Example: - * 

- *  Timer timer = new Timer();
- *  TimerTask task = new TimerTask() {
- *      public void run() {
- *      if (this.scheduledExecutionTime() < System.currentTimeMillis() + 500)

- *      else
- *          // Complain: We are more then half a second late!
- *      if (someStopCondition)
- *          this.cancel(); // This was our last execution
- *  };
- *  timer.scheduleAtFixedRate(task, 1000, 1000); // schedule every second
- *
- *

- * Note that a TimerTask object is a one shot object and can only given once - * to a Timer. (The Timer will use the TimerTask object for bookkeeping, - * in this implementation). - *
