Java Timer Every X Seconds
提问by Grim Reaper
So, I basically need a command to run every 5 seconds, but the Timer doesn't work... I tried so many different methods, The only thing that works is the Thread.sleep(Milliseconds); But that causes my whole game to stop working... If I try using a timer, for example:
所以，我基本上需要一个命令每 5 秒运行一次，但是 Timer 不起作用......我尝试了很多不同的方法，唯一有效的是 Thread.sleep(Milliseconds); 但这会导致我的整个游戏停止工作......如果我尝试使用计时器，例如：
Timer timer = new Timer(1000, new ActionListener(){
@Override
public void actionPerformed(ActionEvent e) {
System.out.println("Hey");
}
});
timer.setRepeats(true);
timer.setCoalesce(true);
timer.start();
How can I get this timer to fire correctly?
我怎样才能让这个计时器正确触发？

You should pair java.util.Timerwith java.util.TimerTask
你应该配对java.util.Timer使用java.util.TimerTask
Timer t = new Timer( );
t.scheduleAtFixedRate(new TimerTask() {
@Override
public void run() {
System.out.println("Hey");
}
}, 1000,5000);
1000 means 1 second delaybefore get executed
& 5000 means will be repeated every 5 seconds.
1000 表示1 second delay在执行之前 & 5000 表示将是repeated every 5 seconds.
To stop it , simply call t.cancel()
要停止它，只需调用 t.cancel()
