兔子乌龟赛跑的案例

package com.pln.thread;
public class Race implements Runnable{
    private String winner;
    @Override
    public void run() {
        for (int i = 0; i <=100 ; i++) {
//            让兔子睡觉
            if(Thread.currentThread().getName()=="兔子" && i%10 == 0){
                try {
                    Thread.sleep(200);
                } catch (InterruptedException e) {
                    e.printStackTrace();
                }
            }
//            如果flag等于true说明比赛结束
            Boolean flag = gameOver(i);
            if(flag){
                break;
            }
            System.out.println(Thread.currentThread().getName()+"--->跑了"+i+"步");
        }
    }
//    判断比赛结束
    private boolean gameOver(int steps){
        if(winner != null){
            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) {
        Race race = new Race();
        new Thread(race,"兔子").start();
        new Thread(race,"乌龟").start();
    }
}

结果：
