java - 如果线程未被阻塞，Thread.interrupt() 会做什么？

Question

Thread 的 JavaDoc 说 Thread.interrupt() 中断线程如下:

• Threads blocked in one of Object's wait() methods or one of Thread's join() or sleep() methods will be woken up, their interrupt status will be cleared, and they receive an InterruptedException.
• Threads blocked in an I/O operation of an InterruptibleChannel will have their interrupt status set and receive an ClosedByInterruptException. Also, the channel will be closed.
• Threads blocked in a Selector will have their interrupt status set and return immediately. They don't receive an exception in this case.

如果线程不满足上述任何条件怎么办？它是被杀死还是继续运行还是什么？

提前致谢...

如果被中断的线程不检查 Thread.isInterrupted() 并对其进行处理，那么在未阻塞的线程上调用 Thread.interrupt() 会有效除了简单地设置标志之外别无他法。线程实现者的工作是使用 Thread.isInterrupted() 正确检查线程的状态并采取适当的操作。
