Thread.sleep（）在从多个线程调用时如何工作 [英] How does Thread.sleep() work when called from multiple threads

问题描述

sleep（）是Thread类的静态方法。从多个线程调用时它是如何工作的。以及它如何找出当前的执行线程。 ？

sleep() is a static method of class Thread. How does it work when called from multiple threads. and how does it figure out the current thread of execution. ?

或者可能是更通用的问题将是如何从不同的线程调用静态方法？不存在任何并发问题吗？

or may be a more generic Question would be How are static methods called from different threads ? Won't there be any concurrency problems ?

推荐答案

如何计算出当前的
执行线程？

how does it figure out the current thread of execution?

它没有。它只调用操作系统，它总是睡眠调用它的线程。

It doesn't have to. It just calls the operating system, which always sleeps the thread that called it.
