Java Thread every X seconds
提问by Manuel Selva
What is the easiest way to have a piece of Java code scheduled at a given rate ?
以给定速率安排一段 Java 代码的最简单方法是什么？

In Java 5+ with a ScheduledExecutorService:
在 Java 5+ 中带有ScheduledExecutorService：
ScheduledExecutorService exec = Executors.newSingleThreadScheduledExecutor();
exec.scheduleAtFixedRate(new Runnable() {
@Override
public void run() {
// do stuff
}
}, 0, 5, TimeUnit.SECONDS);
The above method is favoured. Prior to Java 5 you used Timerand TimerTask:
上面的方法是首选。在 Java 5 之前，您使用Timer和TimerTask：
timer.scheduleAtFixedRate(new TimerTask() {
@Override
public void run() {
// do staff
}
}, 0, 5000);

By using a ScheduledExecutorService.
Have a look at Executors.newScheduledThreadPool. It will allow you to created a ScheduledExecutorServicewhich lets you submit Runnables to be executed at regular intervals.
看看Executors.newScheduledThreadPool。它将允许您创建 a ScheduledExecutorService，让您提交Runnables 以定期执行。

while (true) {
thread.sleep(1000)
method();
}
In many cases there will be better alternatives. But this is the easiest way to implement a regular execution of your method() at an interval of 1000ms + n (where n is the amount of time spent executing method())
在许多情况下，会有更好的选择。但这是以 1000 毫秒 + n 的间隔定期执行 method() 的最简单方法（其中 n 是执行 method() 所花费的时间）
Of course instead of 1000, you can put any millisecond value you desire. It could also be an idea to implement the while loop on a flag that another thread controls; so that there is an way to stop execution of the loop without having to kill the program.
当然，您可以输入任何您想要的毫秒值而不是 1000。在另一个线程控制的标志上实现 while 循环也可能是一个想法；这样就有一种方法可以在不必终止程序的情况下停止循环的执行。

Use below code :
使用以下代码：
Timer timer = new Timer();
timer.schedule( new TimerTask()
{
public void run() {
// do your work
}
}, 0, 60*(1000*1));
