多线程实现龟兔赛跑的java代码

话不多说,先上代码:

package com.qiu.demo01;
//模拟龟兔赛跑
public class Race implements Runnable{
    //胜利者
    private static String winner;
    @Override
    public void run() {
        for (int i = 0; i <=100 ; i++) {
            //模拟兔子休息
            if (Thread.currentThread().getName().equals("兔子")){
                try {
                    Thread.sleep(1/10);
                } catch (InterruptedException e) {
                    e.printStackTrace();
                }
            }
            //判断比赛是否结束
            boolean flag = gameover(i);
            if (flag){
                break;
            }
            System.out.println(Thread.currentThread().getName()+"-->跑了" +i+ "步");
        }
    }
    //判断是否完成比赛
    private boolean gameover(int steps){
        //判断是否有胜利者
        if (winner!=null){
            //已经存在一个胜利者了
            return true;
        }
        {
            if (steps>=100){
                winner=Thread.currentThread().getName();
                System.out.println("winner is"+winner);
                return true;
            }
        }
        return false;
    }

​    public static void main(String[] args) {
​        //一个对象,两个线程.(一条赛道,两个任务)
​        Race race = new Race();
​        new Thread(race,"兔子").start();
​        new Thread(race,"乌龟").start();
​    }
}
