Java 学习笔记之 线程isInterrupted方法

线程isInterrupted方法:

 

isInterrupted()是Thread对象的方法，测试线程是否已经中断。

public class ThreadRunMain {
    public static void main(String[] args) {
        testMainIsInterruptThread();
    }

    public static void testMainIsInterruptThread(){
        Thread.currentThread().interrupt();
        System.out.println("First call: " + Thread.currentThread().isInterrupted());
        System.out.println("Second call: " + Thread.currentThread().isInterrupted());
        System.out.println("end!");
    }
}

运行结果：

public class IsInterruptThread  extends Thread{
    @Override
    public void run() {
        for (int i = 0; i< 5000000; i++){
            System.out.println("i=" + (i + 1));
        }
    }
}

public class ThreadRunMain {
    public static void main(String[] args) {
        testIsInterruptThread();
    }


    public static void testIsInterruptThread(){
        try {
            IsInterruptThread iit = new IsInterruptThread();
            iit.start();
            Thread.sleep(1000);
            iit.interrupt();
            System.out.println("First call: " + iit.isInterrupted());
            System.out.println("Second call: " + iit.isInterrupted());
        } catch (InterruptedException e) {
            System.out.println("Main catch");
            e.printStackTrace();
        }
        System.out.println("end!");
    }
}

运行结果：
