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:
