Java计时器在每t秒后调用函数n次 [英] Java Timer to call function n times after every t seconds

问题描述

我希望 Java Timer 在每 t 秒后调用函数 n 次.我现在正在尝试这个它每隔 t 秒调用一次函数，但我希望这个函数只被调用 n 次.

I want Java Timer to call function n times after every t seconds. I am trying this right now it calls function after every t seconds but I want this function to be called for only n times.

Timer tt = new Timer();
tt.schedule(new MyTimer(url), t);

推荐答案

我认为 Timer 没有将其作为内置函数.您需要添加一个计数器来为每次调用计数，然后在 n 次后使用 cancel() 停止计时器.

I think Timer doesn't have it as a built-in function. You will need to add a counter to count it for each call and then stop the timer using cancel() after n times.

像这样:

final int[] counter = {n};
final Timer tt = new Timer();
tt.schedule(new TimerTask(){
    public void run() {
        //your job
        counter[0]--;
        if (counter[0] == 0) {
            tt.cancel();
        }
    }
}, t);
