java多线程interrupt()函数中断没有拿到锁的wait()的线程

当一个线程在就绪状态&＃xff0c;拿到同步锁&＃xff0c;调用(锁对象.wait())函数之后&＃xff0c;让出锁&＃xff0c;进入锁对象的等待池。如果这个时候&＃xff0c;另一个线程占用锁&＃xff0c;但是这时候调用了阻塞线程的interrupt()函数。阻塞线程并不会立即中断&＃xff0c;它是等待别的线程让出锁之后&＃xff0c;它抢到锁&＃xff0c;再中断的。我做了一个实验如下。

package myThread;// 锁对象
class MyInterruptLock {}public class MyInterrupted {public static void main(String[] args){// 新建锁对象MyInterruptLock myInterruptLock &＃61; new MyInterruptLock();// 新建线程&＃xff0c;让该线程调用wait()函数WaitThread waitThread &＃61; new WaitThread(myInterruptLock, true);// 新建线程&＃xff0c;让该对象调用sleep()函数&＃xff0c;不让出同步锁WaitThread waitThread1 &＃61; new WaitThread(myInterruptLock, false);Thread thread &＃61; new Thread(waitThread,"线程1");Thread thread1 &＃61; new Thread(waitThread1,"线程2");// 启动两个线程thread.start();thread1.start();// 让主线程休息3秒后,中断线程1&＃xff0c;但是线程2占用了同步锁6秒&＃xff0c;可以看出3秒后线程1// 并不会产生异常而中断&＃xff0c;而是6秒后等待线程2执行完&＃xff0c;让出锁&＃xff0c;线程1抢到锁&＃xff0c;才能// 产生异常而中断try {Thread.sleep(3000);thread.interrupt();} catch (InterruptedException e) {e.printStackTrace();}}
}class WaitThread implements Runnable {MyInterruptLock myInterruptLock;boolean flag;public WaitThread(MyInterruptLock myInterruptLock, boolean flag) {this.myInterruptLock &＃61; myInterruptLock;this.flag &＃61; flag;}&＃64;Overridepublic void run() {synchronized (myInterruptLock){System.out.println(Thread.currentThread().getName());if(flag){try {myInterruptLock.wait();} catch (InterruptedException e) {System.out.println("我拿到了锁");e.printStackTrace();}}else{try {Thread.sleep(6000);} catch (InterruptedException e) {e.printStackTrace();}System.out.println("我在占用锁");}}}
}
