如何在特定时间调用方法?
例如在6:00和13:00调用方法。
我正在为 Windows 桌面应用程序工作。
最佳答案
看看 Timer
和 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();
}
}
}
