解释初学者的java代码

I am a beginner java programmer and i saw a code on internet about my projet. But i didn't understand what it does ? Anyone can explain ? What are 1000s ?

我是初学Java程序员,我在互联网上看到了关于我的项目的代码。但我不明白它的作用?谁能解释一下?什么是1000?

private Timer timer = null;
private int timeWorking;

private void xxxxxxxxxxx() {

    if (timer == null) {

        timer = new Timer("Time");
        timer.schedule(new TimerTask() {

            @Override
            public void run() {

                timeWorking++;

            }

        }, 1000, 1000);

    }

}

4 个解决方案

#1

This is a call to java.util.Timer.schedule(TimerTask task, long delay, long period):

这是对java.util.Timer.schedule的调用(TimerTask任务,长延迟,长周期):

Schedules the specified task for repeated fixed-delay execution, beginning after the specified delay.

在指定的延迟之后开始,为重复的固定延迟执行安排指定的任务。

Both delay and period are in milliseconds. 1000 milliseconds are equal to one second.

延迟和周期都以毫秒为单位。 1000毫秒等于一秒。

#2

The see documentation of Timer.schedule()

参见Timer.schedule()的文档

task - task to be scheduled.delay - 
delay in milliseconds before task is to be executed.period - 
time in milliseconds between successive task executions.

#3

See java.util.Timer documentation

请参阅java.util.Timer文档

The first "1000" means delay - delay in milliseconds before task is to be executed. The second "1000" means period - time in milliseconds between successive task executions.

第一个“1000”表示延迟 - 在执行任务之前以毫秒为单位的延迟。第二个“1000”表示连续任务执行之间的时间段(以毫秒为单位)。

#4

public void schedule(TimerTask task, long delay, long period) you are calling this method with delay 1000ms and period 1000ms.

public void schedule(TimerTask任务,长延迟,长时间段)您正在调用此方法,延迟时间为1000毫秒,时间段为1000毫秒。
