如何制作定时器？ [英] How to make a Timer?

问题描述

我想制作等于400 MSc的计时器然后去打印hi！ （例如。）。我知道如何通过 javax.swing.Timer

I want to make a Timer that waits 400 MSc and then goes and prints "hi !" (e.g.). I know how to do that via javax.swing.Timer

    ActionListener action = new ActionListener()
{
    @Override
    public void actionPerformed(ActionEvent e)
    {
       System.out.println("hi!");
    }
};

加：

    timer = new Timer(0, action);
    timer.setRepeats(false);
    timer.setInitialDelay(400);
    timer.start();

但据我所知，这绝对不是一种好方法，因为这种定时器适用于Swing工作。如何以正确的方式做到这一点？ （不使用 Thread.sleep（））

but as I know this definitely is not a good way as this kind of Timer is for Swing works. how to do that in it's correct way? (without using Thread.sleep())

推荐答案

Timer t = new Timer();
t.schedule(new TimerTask() {

            @Override
            public void run() {
                System.out.println("Hi!");

            }
        }, 400);
