Java Thread isInterrupted()方法

Thread類的isInterrupted()方法是一個實例方法，用於測試線程是否已被中斷。 它返回內部標誌的值true或false。 如果線程被中斷，那麼它將返回true，否則返回false。

public boolean isInterrupted()

返回

如果線程已被中斷，它將返回true，否則返回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());
    }
}

執行上面示例代碼，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
