sleep from main thread is throwing InterruptedException
提问by Chris
I have the main thread of execution which spawns new threads. In the main thread of execution in main() I am calling Thread.sleep(). When do I get an Unhandled exceptiontype InterruptedException?.
我有产生新线程的主执行线程。在 main() 的主执行线程中，我正在调用Thread.sleep(). 我什么时候会收到未处理的异常类型InterruptedException？。
I am unsure of why am I getting this. I thought this was because I needed a reference to the main thread so I went ahead and made a reference to it via Thread.currentThread().
我不确定为什么我会得到这个。我认为这是因为我需要对主线程的引用，所以我继续并通过Thread.currentThread().
Is this not the way to have the thread sleep? What I need to do is have the main thread wait/sleep/delay till it does it required work again.
这不是让线程休眠的方法吗？我需要做的是让主线程等待/睡眠/延迟，直到它再次需要工作。

What you see is a compilation error, due to the fact that you didn't handle the checked exception (InterruptedExceptionin this case) properly. Handling means doing one of the following:
您看到的是编译错误，因为您没有正确处理已检查的异常（InterruptedException在本例中）。处理是指执行以下操作之一：
1) Declaring the method as throws InterruptedException, thus requiring the caller to handle the exception
1) 将方法声明为throws InterruptedException，从而要求调用者处理异常
2) Catching it with a try{..}catch(..){..}block. For example:
2) 用try{..}catch(..){..}块抓住它。例如：
try {
Thread.sleep(1500);
} catch(InterruptedException e) {
System.out.println("got interrupted!");
}
InterruptedExceptionis used to indicate that the current thread has been interrupted by an external thread while it was performing some blocking operation (e.g. interruptible IO, wait, sleep)
InterruptedException用于指示当前线程在执行某些阻塞操作（例如可中断 IO、等待、睡眠）时被外部线程中断

Thread.sleep(t);
This is how you can make your thread wait. where t is in milliseconds. It is working fine in my main method, so to find out your problem it would be better if you can provide your code here.
这就是你如何让你的线程等待。其中 t 以毫秒为单位。它在我的主要方法中工作正常，所以如果你能在这里提供你的代码，找出你的问题会更好。

At the line where you're definition of mainstarts, just include throws Exception. I too was facing similar problem, and this helped. After this inclusion, you need not include the Thread.sleep(xx);inside a try-catch statement
在定义main开始的那一行，只包含throws Exception。我也面临着类似的问题，这有帮助。在包含之后，您不需要包含Thread.sleep(xx); 在 try-catch 语句中
