求大神指教

Question

package com.Thread;import sun.rmi.runtime.Log;public class Thread0202 extends Thread { public void run() { Thread0201 t1 = new Thread0201(); Thread0201 t2 = new Thread0201(); // 使用Runnable接口创建线程 Thread one = new Thread(new Thread0201(), "one"); Thread two = new Thread(new Thread0201(), "two"); one.start(); two.start(); // 为什么start一开始 下面的命令不会执行 而且厮杀过程一直不会停止 try { Thread.sleep(50); } catch (InterruptedException e) { e.printStackTrace(); } t1.i = false; t2.i = false; try { two.join(); } catch (InterruptedException e) { e.printStackTrace(); } } public static void main(String[] args) { new Thread0202().start(); }}

Answer 1

因为你start的线程没有用到t1和t2啊。

// 使用Runnable接口创建线程
Thread one = new Thread(new Thread0201(), "one");    // 这里你new了一个Thread0201，应该用t1
Thread two = new Thread(new Thread0201(), "two");  // 这里你new了一个Thread0201，应该用t2
