java中interrupted()和isInterrupted

interrupted():测试当前线程是否已经中断(当前正在执行的线程,是静态方法)。

isInterrupted():测试线程是否已经中断。(对象线程)。

interrupted()方法具有清除状态的功能,isInterrupted()并未清除状态标志。

示例:

public class Run {public static void main(String[] args){MyThread thread=new MyThread();
            thread.start();
        try {Thread.sleep(10);
        } catch (InterruptedException e) {e.printStackTrace();
        }thread.interrupt();
            System.out.println("是否停止1?="+MyThread.interrupted());
            System.out.println("是否停止2?="+MyThread.interrupted());
        System.out.println("end!");
    }
}

i=1

i=2

i=3

i=4

i=5

是否停止1?=false

是否停止2?=false

end!

因为打断的是thread线程,而正在执行的是main线程,所以返回false

改成打断主线程就可以了:

public class Run {public static void main(String[] args){MyThread thread=new MyThread();
            thread.start();
        try {Thread.sleep(10);
        } catch (InterruptedException e) {e.printStackTrace();
        }Thread.currentThread().interrupt();
            System.out.println("是否停止1?="+MyThread.interrupted());
            System.out.println("是否停止2?="+MyThread.interrupted());
        System.out.println("end!");
    }
}

i=1
i=2
i=3
i=4
i=5
是否停止1?=true
是否停止2?=false
end!

public class Run {public static void main(String[] args){MyThread thread=new MyThread();
        thread.start();
        thread.interrupt();
        System.out.println("是否停止1 ? ="+thread.isInterrupted());
        System.out.println("是否停止2 ? ="+thread.isInterrupted());
        System.out.println("end!");
    }
}

是否停止1 ? =true

i=1

是否停止2 ? =true

end!

i=2

i=3

i=4

i=5
