        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;


    @Override
    public 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
