Java Thread isInterrupted()方法

Thread类的isInterrupted()方法是一个实例方法，用于测试线程是否已被中断。 它返回内部标志的值true或false。 如果线程被中断，那么它将返回true，否则返回false。

public boolean isInterrupted()

返回

如果线程已被中断，它将返回true，否则返回false。

示例

public class JavaIsInterruptedExp 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   
    {   
        JavaIsInterruptedExp t1=new JavaIsInterruptedExp();   
        JavaIsInterruptedExp t2=new JavaIsInterruptedExp();   
        // call run() method   
        t1.start();   
        t2.start();  
        System.out.println("is thread interrupted..: "+t1.isInterrupted());  
        System.out.println("is thread interrupted..: "+t2.isInterrupted());  
        // interrupt thread t1   
        t1.interrupt();   
        System.out.println("is thread interrupted..: " +t1.isInterrupted());   
        System.out.println("is thread interrupted..: "+t2.isInterrupted());   
    }  
}

执行上面示例代码，得到以下结果：

is thread interrupted..: false
is thread interrupted..: false
is thread interrupted..: true
is thread interrupted..: false
doing task....: 1
doing task....: 2
doing task....: 3
doing task....: 1
doing task....: 2
doing task....: 3
