问题描述

在某个线程上调用Thread.interrupt()时，该线程会发生什么?

When an Thread.interrupt() is called on some thread, what happens to that thread?

推荐答案

目标线程已中断".通常，在该线程中设置一个标志，该线程可以查看该标志(使用Thread.interrupted()).如果目标线程当前在某些I/O或Object.wait()上被阻塞，则分别通过InterruptedIOException或InterruptedException唤醒它.

The target thread is "interrupted". Mostly, a flag is set in that thread, which the thread can look at (with Thread.interrupted()). If the target thread was currently blocked on some I/O or Object.wait(), then it is awakened with, respectively, an InterruptedIOException or an InterruptedException.

线程中断是微调线程的一种温和方法.与Thread.stop()相反，它用于使线程有机会干净地退出 ，这更像是用突击步枪射击线程.

Thread interruption is a gentle way to nudge a thread. It is used to give threads a chance to exit cleanly, as opposed to Thread.stop(), which is more like shooting the thread with an assault rifle.
