interrupt when sleep

public class Test {
    public static void main(String[] args) throws InterruptedException {
        Thread t1 = new Thread(){
            @Override
            public void run() {
                while(true){
                    if(Thread.currentThread().isInterrupted()){
                        System.out.println("interrupt");
                        break;
                    }
                    try {
                        Thread.sleep(1000);//breakpoint
                    } catch (InterruptedException e) {
                        System.out.println("interrupt when sleep");
                        Thread.currentThread().interrupt();
                    }
                    Thread.yield();
                }
            }
        };
        t1.start();
        Thread.sleep(1000);//breakpoint
        t1.interrupt();

    }

重點:

1.線程睡眠(sleep)時,會丟失中斷(interrupt)標誌
2.中斷線程interrupt,只是對thread設置中斷標誌,並不會結束線程
3.interrupt不會釋放監視器(鎖)
