JUC学习-10-打断线程

# 判断当前线程是否被打断，清除打断标记
pubilc static boolean interrupted()
# 判断当前线程是否被打断，不清除打断标记
public boolean isInterrupted()

一、静态打断方法 并且清除打断标记

可以看到，虽然在sleep方法后调用了interrupted()打断方法，但是并没有抛出异常。

class TestInterrupted {

	static Thread t1 = new Thread() {
		@Override
		public void run() {
			try {
				System.out.println(Thread.interrupted() + "");
				TimeUnit.SECONDS.sleep(2);
			} catch (InterruptedException e) {
				throw new RuntimeException(e);
			}
		}
	};

	public static void main(String[] args) {
		t1.start();
		t1.interrupt();
	}

}

运行结果：

二、不清除打断标记

调用sleep()方法后再调用isInterrupted()方法，此时会抛出异常：java.lang.InterruptedException: sleep interrupted

class TestInterrupted {

	static Thread t1 = new Thread() {
		@Override
		public void run() {
			try {
//                System.out.println(Thread.interrupted() + "");
				// 不清除打断标记
				System.out.println(currentThread().isInterrupted());
				TimeUnit.SECONDS.sleep(2);
			} catch (InterruptedException e) {
				throw new RuntimeException(e);
			}
			System.out.println("线程睡眠结束");
		}
	};

	public static void main(String[] args) {
		t1.start();
		t1.interrupt();
	}

}
