Java Thread interrupted()方法

Thread類的interrupted()方法用於檢查當前線程是否已被中斷。 此方法清除線程的中斷狀態，這意味著如果要連續兩次調用此方法，則第二次調用將返回false。 如果線程的中斷狀態為true，則此方法將狀態設置為false。

語法

public static boolean interrupted()

返回
如果當前線程已被中斷，則此方法將返回true，否則返回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());
    }
}

執行上面示例代碼，得到以下結果：

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
