Java中定时调用方法

如何在特定时间调用方法？

例如在6:00和13:00调用该方法。

我正在开发 Windows 桌面应用程序。

看看Timer and TimerTask类。您可以安排线程在特定时间或重复执行。

public class Alarm {
    Timer _timer;

    public Alarm() {

        // Create a Date corresponding to 10:30:00 AM today.
        Calendar calendar = Calendar.getInstance();
        calendar.set(Calendar.HOUR_OF_DAY, 10);
        calendar.set(Calendar.MINUTE, 30);
        calendar.set(Calendar.SECOND, 0);

        Date alarmTime = calendar.getTime();

        _timer = new Timer();
        _timer.schedule(new AlarmTask(), alarmTime);
    }

    class AlarmTask extends TimerTask {
        /**
         * Called on a background thread by Timer
         */
        public void run() {
            // Do your work here; it's 10:30 AM!

            // If you don't want the alarm to go off again
            // tomorrow (etc), cancel the timer
            timer.cancel();
        }
    }
}
