java - 如何判断Timer任务是否完成

Question

我有以下代码:

Timer timer = new Timer();      
TimerTask task = new TimerTask() {

    @Override
    public void run() {
        // TODO Auto-generated method stub
    }
};

timer.schedule(task, 10000);//execute after 10 seconds

我们能否确定任务是否已被计时器执行或仍在到期？

Answer 1

添加一个简单的变量，比如..

  boolean isTaskCompleted = false;
  Timer timer = new Timer();      
  TimerTask task = new TimerTask() {

     @Override
     public void run() {
        // do stuff
        isTaskCompleted = true;
     }
  };

  timer.schedule(task, 10000);//execute after 10 seconds
