Java程序演示interrupted()方法的示例 (Java program to demonstrate example of interrupted() method)

/*  We will use Thread class methods so we are importing
the package but it is not mandate because
it is imported by default
*/
import java.lang.Thread;
class InterruptedThread extends Thread
{
// Overrides run()  method of Thread class
public void run()
{for(int i=0;i<=3;++i){/*  By using interrupted() method to check whether
this thread has been interrupted or not it will
return and execute the interrupted code
*/
if(Thread.interrupted())
{System.out.println("Is thread" +Thread.currentThread().getName()+"has been interrupted and status is set to "+" " +Thread.interrupted());
}
else
{System.out.println("This thread has not been interrupted");
}
}
}
public static void main(String args[])
{
InterruptedThread it1 = new InterruptedThread();
InterruptedThread it2 = new InterruptedThread();
/*  By using start() method to call the run() method of
Thread class and Thread class start() will call run()
method of InterruptedThread class
*/
it2.start();
it2.interrupt();
it1.start();
}
}
