Java Thread interrupted()方法

Thread类的interrupted()方法用于检查当前线程是否已被中断。 此方法清除线程的中断状态，这意味着如果要连续两次调用此方法，则第二次调用将返回false。 如果线程的中断状态为true，则此方法将状态设置为false。

语法

public static boolean interrupted()

返回
如果当前线程已被中断，则此方法将返回true，否则返回false。

示例

public class JavaInterruptedExp extends Thread   
{   
    public void run()   
    {   
        for(int i=1;i<=3;i++)   
        {   
            System.out.println("doing task....: "+i);   
        }   
    }   
    public static void main(String args[])throws InterruptedException   
    {   
        JavaInterruptedExp t1=new JavaInterruptedExp();   
        JavaInterruptedExp t2=new JavaInterruptedExp();   
        // call run() method   
        t1.start();   
        t2.start();  
        System.out.println("is thread t1 interrupted..: "+t1.interrupted());  
        // interrupt thread t1   
        t1.interrupt();   
        System.out.println("is thread t1 interrupted..: " +t1.interrupted());   
        System.out.println("is thread t2 interrupted..: "+t2.interrupted());   
    }  
}

执行上面示例代码，得到以下结果：

is thread t1 interrupted..: false
is thread t1 interrupted..: false
is thread t2 interrupted..: false
doing task....: 1
doing task....: 2
doing task....: 3
doing task....: 1
doing task....: 2
doing task....: 3
