在Thread.join（）之前调用Thread.interrupt（）会导致join（）立即抛出一个InterruptedException？ [英] Does calling Thread.interrupt() before a Thread.join() cause the join() to throw an InterruptedException immediately?

问题描述

基本上，问题标题是什么。

Basically, what the question title says.

Thread t = new Thread(someRunnable);
t.start();
t.interrupt();
t.join(); //does an InterruptedException get thrown immediately here?

从我自己的测试，似乎，但只是想确定。我猜在 Thread.join（）检查中断状态的线程之前做等待例程？

From my own tests, it seems to, but just wanted to be sure. I'm guessing Thread.join() checks the interrupted status of the thread before doing its "wait" routine?

推荐答案

interrupt（）中断您中断的线程，做中断。

interrupt() interrupts the thread you interrupted, not the thread doing the interrupting.

cf

Thread.currentThread().interrupt();
t.join(); // will throw InterruptedException
