　　這裡我們通過執行個體來學習一下java多線程中關於interrupt方法的一些知識。

 

java多線程中的interrupt執行個體一、java中的interrupt的使用

public class InterruptTest {    public static void main(String[] args) {        MyThread1 myThread1 = new MyThread1();        myThread1.start();        myThread1.interrupt();        System.out.println("isInterrupted is " + myThread1.isInterrupted()); // true        System.out.println("isInterrupted is " + myThread1.interrupted()); // false    }    static class MyThread1 extends Thread {        @Override        public void run() {            try {　　　　　　　　　// The interrupted status of the thread is cleared by this method                System.out.println("in isInterrupted is " + Thread.interrupted()); // true                System.out.println("isInterrupted is " + Thread.currentThread().isInterrupted()); // false                TimeUnit.SECONDS.sleep(5);                System.out.println("my thread 1");            } catch (InterruptedException e) {                e.printStackTrace();            }        }    }}

 如果注釋掉代碼：System.out.println("in isInterrupted is " + Thread.interrupted());則列印的結果如下：

isInterrupted is trueisInterrupted is falseisInterrupted is truejava.lang.InterruptedException: sleep interrupted    at java.lang.Thread.sleep(Native Method)    at java.lang.Thread.sleep(Thread.java:340)    at java.util.concurrent.TimeUnit.sleep(TimeUnit.java:360)    at com.linux.huhx.thread2.InterruptTest$MyThread1.run(InterruptTest.java:21)

 

二、多線程中的中斷停止線程運行

public class InterruptTest {    public static void main(String[] args) throws Exception {        MyThread1 myThread1 = new MyThread1();        myThread1.start();        myThread1.interrupt();        System.out.println("isInterrupted is " + myThread1.isInterrupted()); // true        System.out.println("isInterrupted is " + myThread1.interrupted()); // false    }    static class MyThread1 extends Thread {        @Override        public void run() {            while (true) {                if (Thread.interrupted()) {                    System.out.println("break");                    break;                }                System.out.println("count " + Thread.currentThread().isInterrupted()); // count false            }        }    }}

一次的運行結果如下：

isInterrupted is trueisInterrupted is falsebreak
