java 子线程A如何终止子线程B

Question

这是我的代码，问题是子线程 T1 并未终止子线程 T ，请看源码

public class ThreadExit {
    public static void main(String[] args) {
        T1 t1 = new T1();
        Thread thread = new Thread(t1);
        thread.start();

        T t = new T();
        t.start();

    }
}

class T extends Thread {

    private int count = 0;
    private boolean loop = true;
    @SuppressWarnings("all")
    @Override
    public void run() {
        while(loop){
            try {
                Thread.sleep(1000);
            } catch (InterruptedException e) {
                e.printStackTrace();
            }
            System.out.println("Thread T in progress..." + (++count));
        }
    }

    public void setLoop(boolean loop) {
        this.loop = loop;
    }
}

class T1 implements Runnable {

    @Override
    public void run() {
        T t = new T();
        System.out.println("Thread T1 whill to sleep for 5s ...");
        try {
            Thread.sleep(5000);
        } catch (InterruptedException e) {
            e.printStackTrace();
        }
        System.out.println("Thread T1'll stop T, T are about to exit !");
        t.setLoop(false);
    }
}

你认为你在t1里面new的T 和main方法里面的t，数据会是一个嘛？
