具有非固定延迟的Java计时器 [英] Java timer with not-fixed delay

问题描述

我需要一个计时器，基本上每t秒做一次。但我希望能够修改计时器重复任务的计时器周期。我写了这样的东西：

I need a Timer that basicaly does something every t seconds. But I want to be able to modify the timer period at which the timer repeats the task. I wrote something like this:

public Bot() {
    timer = new Timer();
    timer.schedule(new Task(), 1000, moveTime = 1000);          
}

public class Task extends TimerTask {
    @Override
    public void run() {
        System.out.println("Time Passed from last repeat:" + movetime)
        moveTime += 1000;
    }

因此，在1000ms延迟后计时器启动并重复每个 moveTime ms。问题是即使我将 movetime 增加1000，计时器总是以初始延迟（1000）运行，但值 movetime 每次定时器调用 run（）时，增加（2000,3000,4000等）。

So, After 1000ms delay the timer starts and repeats every moveTime ms. The problem is even if I increased movetime by 1000, the timer always runs at initial delay(1000) but the value of movetime increases(2000,3000,4000 etc) each time the timer calls run().

我是否遗漏了某些东西，或者我有什么选择，每隔't'秒重复一次任务，其中't'是可变的？

Am I missing something or what alternative do I have for repeating a task every 't' second with 't' being variable?

谢谢。

推荐答案

我不认为 java.util。计时器类支持这个。

你能做的就是使用 Timer.schedule（TimerTask，int）在一定时间后执行任务的方法。当你的任务被执行时，你可以用你想要的新间隔安排一个新的计时器。

Something you can do is use the Timer.schedule(TimerTask, int) method that executes your task one after a certain amount of time. When your task gets executed, you can then scheduled a new timer with the new interval you want.

类似的东西：

int moveTime = 1000;

Timer timer = new Timer();

public Bot(){
    timer.schedule(new Task(), moveTime);
}

public class Task extends TimerTask {
    @Override
    public void run() {
        System.out.println("Time Passed from last repeat:"+movetime)
        moveTime += 1000;
        timer.schedule(new Task(), moveTime)
    }
}
