package org.example;public class Race implements Runnable {//胜利者private static String winner;@Overridepublic void run() {for(int i=0;i<=100;i++){boolean flag =gameOver(i);//如果flag>=100,结束比赛if(flag){break;}System.out.println(Thread.currentThread().getName()+"跑了"+i+"米");}}//判断比赛是否结束private boolean gameOver(int a){if(winner!=null){return true;}{if(a==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();}
}

 

   winner=Thread.currentThread().getName();  获取进程的名字

如果兔子中途睡觉

public class Race implements Runnable {//胜利者private static String winner;@Overridepublic void run() {for(int i=0;i<=100;i++){if(Thread.currentThread().getName().equals("兔子")&& i%5==0){try {Thread.sleep(1);} catch (InterruptedException e) {throw new RuntimeException(e);}}boolean flag =gameOver(i);if(flag){break;}System.out.println(Thread.currentThread().getName()+"跑了"+i+"米");}}private boolean gameOver(int a){if(winner!=null){return true;}{if(a==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();}
}

其中i%5==0是定义兔子跑了多少步开始睡觉
