每10分钟调用一次函数 [英] Calling a function every 10 minutes

问题描述

我不是专家，只是初学者。所以我恳请你为我写一些代码。

I'm not an expert, just a beginner. So I kindly ask that you write some code for me.

如果我有两个班级， CLASS A 和 CLASS B ，并且在 CLASS B 里面有一个名为的函数funb（）。我想每隔十分钟从 CLASS A 调用此函数。

If I have two classes, CLASS A and CLASS B, and inside CLASS B there is a function called funb(). I want to call this function from CLASS A every ten minutes.

你已经给了我一些想法，不过我不太明白。

You have already given me some ideas, however I didn't quite understand.

你能发布一些示例代码吗？

Can you post some example code, please?

推荐答案

查看 ScheduledExecutorService ：

这是一个类，其方法设置ScheduledExecutorService每隔十秒钟发出一小时的哔声：

Here is a class with a method that sets up a ScheduledExecutorService to beep every ten seconds for an hour:

 import static java.util.concurrent.TimeUnit.*;
 class BeeperControl {
    private final ScheduledExecutorService scheduler =
       Executors.newScheduledThreadPool(1);

    public void beepForAnHour() {
        final Runnable beeper = new Runnable() {
                public void run() { System.out.println("beep"); }
            };
        final ScheduledFuture<?> beeperHandle =
            scheduler.scheduleAtFixedRate(beeper, 10, 10, SECONDS);
        scheduler.schedule(new Runnable() {
                public void run() { beeperHandle.cancel(true); }
            }, 60 * 60, SECONDS);
    }
 }
