Java Thread isInterrupted()方法

Thread類的isInterrupted()方法是一個範例方法，用於測試執行緒是否已被中斷。 它返回內部標誌的值true或false。 如果執行緒被中斷，那麼它將返回true，否則返回false。

public boolean isInterrupted()

返回

如果執行緒已被中斷，它將返回true，否則返回false。

範例

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());   
    }  
}

執行上面範例程式碼，得到以下結果：

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
