我调用interrupt方法中断线程后,isInterrupted仍然为false。看代码第二个注释处
public class InterruptThread
{
public static void main(String[] args) {
Mythread mythread= new Mythread();
mythread.start();
try {
Thread.sleep(10000);//主线程休眠十秒,让子线程执行十秒,然后中断mythread子线程
mythread.interrupt();
Thread.sleep(3000);
//明明调用了mythread.interrupt(),下面这句却还是false,这是为何?
System.out.println("线程是否已经中断:"+mythread.isInterrupted());
System.out.println("线程是否已经中断:"+mythread.interrupted());
} catch (InterruptedException e) {
e.printStackTrace();
}
}
}
class Mythread extends Thread{
@Override
public void run(){
try {
while(true){
interruptableMethod();
}
}
catch (InterruptedException e) {
System.out.println(Thread.currentThread().getName()+"线程中断了");
}
}
public void interruptableMethod() throws InterruptedException{
System.out.println("方法开始执行");
sleep(2000);
System.out.println("方法结束");
}
}
