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?
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
