如果在睡眠线程上调用interrupt()会发生什么? [英] What will happen if you call interrupt() on a sleeping thread?

问题描述

我有一个线程，在run()上我呼叫sleep().如果我中断该线程会怎样?

I have a thread, and on run() I call sleep(). What will happen if I interrupt this thread?

MyThread extends Thread{
    public void run(){
          try{
             sleep(1000000);
          } catch(InterruptedException e) {//}
    }    
}

我想澄清以下内容:

• 如果线程尚未启动，则调用interrupt()不会执行任何操作，对吧?
• 如果线程已启动并且现在正在休眠，则在休眠时调用interrupt()会抛出InterruptedException；因此，转到catch()然后结束线程，对吗?

• If the thread is not yet started, calling interrupt() would do nothing, right?
• If the thread is started, and is now sleeping, calling interrupt() while sleeping will throw an InterruptedException; and thus, goes to catch() and then ends the thread, right?

推荐答案

1)Thread.interrupt API:中断未运行的线程不会产生任何效果.

1) Thread.interrupt API: Interrupting a thread that is not alive need not have any effect.

2)在您的示例中，被中断的线程将进入catch块，然后离开run方法并终止

2) In your example the interrupted thread will enter catch block then leave run method and terminate
