如何捕捉一个InterruptedException?详情请进

[Patrick_DK]

小弟写了个程序，想捕捉一个InterruptedException，但是没有实现，请高手帮我改一下，以实现catch(InnterruptedException ie)中的语句

public class SL275 implements Runnable
{
public static void main(String[] args)
{
SL275 s=new SL275();
Thread t=new Thread(s);
t.start();
}

public void run()
{
try
{
Thread.sleep(1000);
Thread.interrupted();
}
catch(InterruptedException ie)
{
System.out.println("catch an interruptedexception");
}
finally
{
System.out.println("Implement Runnable Interface");
}
}
}

根据你的提示我改了程序，可以捕捉到异常了，但是在下面这个程序中，把interrupted（）方法放在哪里，会返回true啊？

public class SL275 implements Runnable
{
public static void main(String[] args)
{
SL275 s=new SL275();
Thread t=new Thread(s);
t.start();
t.interrupt();
}

public void run()
{
try
{
System.out.println("Sleep");
Thread.sleep(1000);

}
catch(InterruptedException ie)
{
System.out.println("Catch an interruptedexception");
}
}
}

throw new InterruptedException("");

to 路人甲大哥：

我在看MyNote的时候看到一段话
If interrupt method is invoked on a sleeping thread, the thread moves to ready state. The next time it begins running, it executes the InterruptedException handler.

我的意思是想实现这段话所说的

interrupted()是测试当前线程是否被打断
应该调用interrupt（）；
interrupt使sleep和wait状态的线程从这两个方法中抛出InterruptedException
interrupt应从别的线程调用。

如：

Thread t = new Thread(){
public void run(){
try
{
Thread.sleep(5000);
System.out.println("wake up");
}
catch(InterruptedException ie)
{
System.out.println("interrupted!");
}
}
};



t.start();
try{
Thread.sleep(1000);
}
catch(InterruptedException ie){}
t.interrupt();

[wangtaoyy]

InterruptedException 捕获以后interrupted（）应该返回true;

[wangtaoyy]

catch(InterruptedException ie)
{
System.out.println("Catch an interruptedexception");
System.out.println("thread interrupted :" + interrupted（) );
}

interrupted()实际上经常用来判断当前线程是正常结束等待还是被打断
