[JavaEE]如何唤醒Sleep中的线程

主线程调用子线程的interrupt()方法，导致子线程抛出InterruptedException， 在子线程中catch这个Exception，不做任何事即可从Sleep状态唤醒线程，继续执行。 如下测试。

public class SleepThreadTest { public static void main(String[] args){ Thread myThread = new Thread(new TestThread(1)); myThread.start(); try { Thread.sleep(3000); myThread.interrupt(); } catch (InterruptedException e) { e.printStackTrace(); } } private static class TestThread implements Runnable{ private int i; public TestThread(int i){ this.i = i; } @Override public void run() { while(i<10){ System.out.println(i + " time:" + new Date()); i++; if(i==4){ try { Thread.sleep(10000); } catch (InterruptedException e1) { System.out.println("interrupt myThread..."); } } } } }}

result:
