JAVA使时间通过摆动定时器减少到零 [英] JAVA making time to decrease to zero by swing timer

问题描述

我有一个毫秒，我将它转换为 hh:mm:ss 现在我想让它自动减少超时值.. 倒数计时器之类的东西

I have a milliseconds and i convert it hh:mm:ss now i want to make it to automatically decrease value overtime.. something like countdown timer

例如，当用户看到它时，2:11 0 -> 2:10 59 -> 2:10 58 ...

for example, when user sees it, 2:11 0 -> 2:10 59 -> 2:10 58 ...

下面是我的代码..

        Timer t = new Timer(1000, new ActionListener() {
            public void actionPerformed(ActionEvent e) {

                int s = ((TIMER/1000) % 60);
                int m = (((TIMER/1000) / 60) % 60);
                int h = ((((TIMER/1000) / 60) /60) % 60);

                timing.setText(hour + " hours, " + min + " minutes" + sec + " seconds");
                timing.repaint();
}
}
t.start();

有可能吗?

推荐答案

final Timer t = new Timer(1000, new ActionListener() {
    private long time = 10 * 1000; //10 seconds, for example

    public void actionPerformed(ActionEvent e) {
        if (time >= 0) {
            long s = ((time / 1000) % 60);
            long m = (((time / 1000) / 60) % 60);
            long h = ((((time / 1000) / 60) / 60) % 60);
            timing.setText(h + " hours, " + m + " minutes " + s + " seconds");
            time -= 1000;
        }
    }
});
t.start();
