Intrrupt的使用說明

Intrrupte只是設置了一下線程的中斷狀態，並不是實際的停止線程。具體見下面的例子：

public class InterruptedTest {
	public static void main(String[] args) {
		Runnable runnable1 = new Runnable() {
			
			@Override
			public void run() {
				for (int i = 0; i < 10; i++) {
					System.out.println(i);
					if (Thread.currentThread().isInterrupted()) {
						System.out.println("aa");
						break; //退出循環
					}
					try {
						Thread.sleep(1000);
					} catch (InterruptedException e) {
						e.printStackTrace();
						//sleep方法拋出這個異常之後會清除中斷狀態，所以需要重新設置中斷狀態
						Thread.currentThread().interrupt();
					}
				}
			}
		};

		final Thread t1 = new Thread(runnable1);

		Runnable runnable2 = new Runnable() {
			@Override
			public void run() {
				try {
					Thread.sleep(3000);
					t1.interrupt();
				} catch (InterruptedException e) {
					e.printStackTrace();
				}
			}
		};

		Thread t2 = new Thread(runnable2);

		t1.start();
		t2.start();
	}
}
