//使用Thread自带的标志位
public class Demo2 {
    public static void main(String[] args) {
        Thread thread=new Thread(()->{
            //调用currentThread（）静态方法可以获得当前线程的对象，也就是定义好了的thread
            // 再用这个对象去调用isInterrupted（）方法获得Thread自带的标志位
            while (!Thread.currentThread().isInterrupted()){    //Thread.currentThread().isInterrupted()可以用Thread.interrupted()代替
                                                                // 但是不建议，因为interrupted（）方法会在判定标志位的同时清除标志位
                System.out.println("hello thread");

                    Thread.sleep(1000);

        }
        thread.interrupt(); //调用interrupt（）方法时要是线程正在sleep当中就会强制使sleep抛出一个异常，立即唤醒，但是sleep唤醒了以后
                            //会自动清除前面设置的标志位，给程序员留下更多的操作空间（接下来的操作在catch中写，比如要终止线程，就在catch中写break）
