你怎么java.lang.Thread在Java中杀了？

Thread currentThread=Thread.currentThread();
        public void run()
        {               

             while(!shutdown)
            {                               
                try
                {
                    System.out.println(currentThread.isAlive());
                Thread.interrupted();

                System.out.println(currentThread.isAlive());
                if(currentThread.isAlive()==false)
                {
                    shutdown=true;
                }
                }
                catch(Exception e)
                {
                    currentThread.interrupt();
                }                   
            }
        }

    });
    thread.start();

我试图阻止一个线程,但我不能这样做:

public class Middleware {

public void read() {
    try {
        socket = new Socket("192.168.1.8", 2001);

        // code .. 

        Scan scan = new Scan();
        thread = new Thread(scan);
        thread.start();

    } catch (UnknownHostException ex) {
        ex.printStackTrace();

    } catch (IOException ex) {
        ex.printStackTrace();
    }
}

class Scan extends Thread {

    public void run() {

        while (true) {
            try {
            // my code goes here

            } catch (IOException ex) {
                thread.currentThread().interrupt();
            }
        }
    }
}

public void stop() {
    Thread.currentThread().interrupt();
}

// get …

我试图在以下代码中终止线程:

public synchronized void run() {
    try {
        while (!Thread.currentThread().isInterrupted()) {
            this.scan();
            this.distribute();
            this.wait();
        }
    } catch (InterruptedException e) {}
}

public void cancel() {
    this.interrupt();
}

但线程不会终止.我使用了调试器并发现在命令之后this.interrupt(),线程没有被中断(我对表达式进行了监视this.isInterrupted()并保持不变false).任何人都知道为什么这个线程不会被打断？

编辑:

问题已经找到.原来这个帖子有两个实例.我附上导致这个问题的有问题的代码:

/* (class Detector extends Thread) */
Detector detector = new Detector(board);
...
Thread tdetector  = new Thread(detector); /* WRONG!!! */
...
tdetector.start();
...
