线程中断

public class ww

public static void main(String[] args)
{
int i;
final Mythread m=new Mythread();
Frame f=new Frame();
f.setSize(555, 555);

f.setLayout(new GridLayout(13,5));
Button b=new Button("按钮");
Button c=new Button("按钮c");

f.add(b);
f.add(c);
f.setVisible(true);

f.addWindowListener(new WindowAdapter()
{
public void windowClosing (WindowEvent e)
{
m.start();
System.out.print(" end");

}
});
}
}



class Mythread extends Thread
{
public void run()
{
for(int i=0;i<12;i++)
{
try
{
Thread.sleep(332);
}
catch (InterruptedException e)
{
e.printStackTrace();
}
if(i==4)
this.interrupt();

System.out.print(i);
}
}
}


运行结果怎么会这样；

at Mythread.run(ww.java:52)

当i=4的时候线程不是应该中断吗，

[eimhee]

当I=4时, 是中断了, 由于I==4时, 那线程处于SLEEP状态, 然后又调用了INTERRUPT()方法, 就会抛出InterruptedException,
在I=5时, e.printStackTrace(); 会退出程序,


线程进行中断就是抛出异常
