java用匿名内部类实现多线程堆内存变量共享

匿名内部类介绍：http://www.cnblogs.com/nerxious/archive/2013/01/25/2876489.html

用Runnable模拟实现共享堆内存变量

import java.lang.Thread;
public class SellTicket {  
  
     /**  
      * 用Runnable模拟实现共享堆内存变量
     * @param args  
     */    
    public static void main(String[] args) {
      Runnable  runnable = new Runnable() {
        private int ticket = 50;
        public void run() {
          while (ticket > 0) {
            ticket--;
            System.out.println(Thread.currentThread().getName()+"当前票数为：" + ticket);
          }
        }
      };
        new Thread(runnable).start();
        new Thread(runnable).start();
    }
}

用Thread模拟实现共享堆内存变量

public class SellTicket2 {  
  
     /**  
      * 用Thread模拟实现共享堆内存变量
     * @param args  
     */    
    public static void main(String[] args) {
      Thread mt = new Thread(){
        private int ticket = 50;
        public void run() {
          while (ticket > 0) {
            ticket--;
            System.out.println(Thread.currentThread().getName()+"当前票数为：" + ticket);
          }
        }
      };
      new Thread(mt).start();;
      new Thread(mt).start();;
    }
}

Runnable和Thread实现多线程，共同点是变量可以共享，区别是用借口实现更加灵活，继承只能单继承有局限性。
