Java 多线程联系6：模拟接力赛跑

需求：

 

实现思路：

 

 1 package JieLiShai;
 2 
 3 /**
 4  * 跑步线程类
 5  */
 6 public class RunThread implements Runnable {
 7     private int meters = 1000; //共跑1000米
 8     public  void run() {
 9         while (true) {
10             if(meters<=100){
11                 break;
12             }
13             go();
14             return;
15         }
16     }
17     //同步方法：跑步（每人跑100米）
18     public synchronized void go(){        
19         System.out.println(Thread.currentThread().getName()+"拿到接力棒！");
20         for (int i = 0; i < 100; i += 10) {
21             try {
22                 Thread.sleep(100);
23             } catch (InterruptedException e) {                    
24                 e.printStackTrace();
25             }
26             System.out.println(Thread.currentThread().getName() + "跑了" + (i + 10)
27                     + "米！");
28         }
29         meters-=100;
30     
31     }
32 }
