一个java的Timer定时器，每隔1秒钟刷新一次JLabel，5秒钟后退出系统。

private void initialTimer() {          Timer timer = new Timer();          timer.schedule(new TimerTask() {              int MAX_COUNTER = 5;              int counter = 0;              @Override              public void run() {                  if (MAX_COUNTER == counter) {                      if (!isExitCB.isSelected()) {                          System.exit(0);                      } else {                          this.cancel();                      }                  }                  willExitLabel.setText("System will exit within "                          + (MAX_COUNTER - counter) + " seconds");                  counter++;              }          }, 0, 1000);  }
