Java Swing:在计时器上设置开始时间并循环播放 [英] Java Swing: Set starting time on timer and loop it

问题描述

我正在使用这个 leepoint.net 上的示例

使用此代码，计时器以实时秒数启动，但我想知道如何实现从 1 秒开始，然后让它运行 10 秒并重新开始?所以从 1 到 10 等等..

with this code the timer starts on real time seconds, but i was wondering how i can make it start at 1 second and then let it run up to 10 seconds and start over? So from 1 to 10 and so on..

class ClockListener implements ActionListener {
        public void actionPerformed(ActionEvent e) {

            Calendar now = Calendar.getInstance();
            int s = now.get(Calendar.SECOND);
            _timeField.setText(String.format("%1$tS", now));

                    }
    }

推荐答案

试试这个

class ClockListener implements ActionListener {
    int count = 0;
    public void actionPerformed(ActionEvent e) {
        int fakeSecond = (count++ % 10) + 1; 
        Calendar now = Calendar.getInstance();
        int h = now.get(Calendar.HOUR_OF_DAY);
        int m = now.get(Calendar.MINUTE);
        int s = now.get(Calendar.SECOND);
        _timeField.setText("" + h + ":" + m + ":" + fakeSecond);
    }
}
