龟兔赛跑代码实现

赛道相当于一个资源，乌龟和兔子相当于两个线程，多线程共用一个资源

package com.demo01;

public class Race implements Runnable{
    private static String winner;
    @Override
    public void run(){

        for(int i=0;i<=100;i++){
            if(Thread.currentThread().getName()=="兔子" && i%20==0){
                try {
                    Thread.sleep(10);
                } catch (InterruptedException e) {
                    e.printStackTrace();
                }
            }
            boolean flag=gameOver(i);
            if(flag){
                break;
            }
            System.out.println(Thread.currentThread().getName()+"跑了"+i+"步");
        }
    }

    private boolean gameOver(int steps){
        if(winner!=null){
            return true;
        }{
            if(steps>=100){
                winner=Thread.currentThread().getName();
                System.out.println("winner is"+Thread.currentThread().getName());
            }
        }
        return false;
    }

    public static void main(String[] args){
        Race race=new Race();
        new Thread(race,"兔子").start();
        new Thread(race,"乌龟").start();

    }
}
