java isInterrupted()判断线程的实例讲解

1、说明

isInterrupted()可以判断当前线程是否被中断，仅仅是对interrupt()标识的一个判断，并不会影响标识发生任何改变（因为调用interrupt()的时候会设置内部的一个叫interrupt flag的标识）。

2、实例

public static void main(String[] args) throws InterruptedException{
    Thread thread = new Thread(()->{
        while (true){}
    });
    thread.start();
    TimeUnit.SECONDS.sleep(1);
    System.out.println("Thread is interrupted :"+thread.isInterrupted());
    thread.interrupt();
    System.out.println("Thread is interrupted :"+thread.isInterrupted());
}

实例扩展补充：

ublic class t12 {
    public static void main(String[] args) {
        try {
            MyThread12 thread = new MyThread12();
            thread.start();
            Thread.sleep(500);
            thread.interrupt();
            System.out.println("是否终止1？ =" + thread.interrupted());
            System.out.println("是否终止2？ =" + thread.interrupted());
        } catch (InterruptedException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
        System.out.println("-------------end-------------");
    }
}

class MyThread12 extends Thread {
    public void run() {
        for (int i = 0; i < 50000; i++) {
            System.out.println("i = " + i);
        }
    }
}
