public class TimeTask {   
   
    public static void main(String[] args) { 
        TimeTask tTask=new TimeTask();
        tTask.timeVoid();
    }
    
    public void timeVoid(){
        final Timer timer = new Timer();
        TimerTask tt=new TimerTask() { 
            @Override
            public void run() {
                System.out.println("到点啦！");
                timer.cancel();
            }
        };
        timer.schedule(tt, 3000);
