java - 从单独的方法关闭计时器

Question

我有一个计时器，其工作原理如下:

public void startTourButton(ActionEvent event) {
new Timer ().schedule(
        new TimerTask () {

            public void run(){          
                     System.out.println("Going to do something here");
            }

        }, 0, 5000);

 }

我正在尝试从此处的不同事件取消计时器:

public void stopTourButton(ActionEvent event) {
Timer.cancel();
   }

我收到错误

Cannot make a static reference to the non-static method cancel() from the type Timer

我该如何解决这个问题？

Answer 1

将计时器保存为类(class)成员，以便稍后可以取消

class YourClass {

    Timer timer;

    public void startTourButton(ActionEvent event) {
        if (timer == null) {
            timer = new Timer();
        }
        timer.schedule(
            new TimerTask () {    
                public void run(){          
                    System.out.println("Going to do something here");
                }   
            }, 0, 5000);
        }
    }

    public void stopTourButton(ActionEvent event) {
        timer.cancel();
        timer = null;
    }
}
