该博客主要围绕使用多线程模拟龟兔赛跑场景展开，给出了实现此模拟的代码，并展示了运行结果，体现了多线程在模拟特定场景中的应用。

题目：使用多线程，模拟龟兔赛跑的场景

代码如下：

package com.day505.testdemo.exam2;

public class RubbitTurtleRun extends Thread{

    //设置长度为1000m
    private int distance = 1000;

    //设置兔子和乌龟每次走的路长度
    int rubbitNum = 40;
    int turtleNum = 20;

    //设置兔子和乌龟已经走的路长度
    int rubbitDistance = 0;
    int turtleDistance = 0;

    boolean flag = true;
    @Override
    public void run() {
        String name = Thread.currentThread().getName();

        while (flag){

            try {
                Thread.sleep(100);
            } catch (InterruptedException e) {
                e.printStackTrace();
            }

            if (name.equals("兔子")){

                rubbitDistance = rubbitDistance+rubbitNum;
                System.out.println(name+"我已经跑了"+rubbitDistance+"米");
                //兔子中间休息了
                if ((rubbitDistance%200==0) && (rubbitDistance<distance)){
                    System.out.println(name+"好累啊，已经跑了"+rubbitDistance+"米，乌龟还在后面，先休息一会吧");
                    try {
                        //兔子休息
                        sleep(650);
                    } catch (InterruptedException e) {
                        e.printStackTrace();
                    }
                }
                if (rubbitDistance == distance){
                    System.out.println("=======兔子赢了============");
                    flag = false;
                    break;
                }
            }

            //乌龟不休息
            if (name.equals("乌龟")){
                turtleDistance = turtleDistance+turtleNum;
                System.out.println(name+"我已经跑了"+turtleDistance+"米");
                if (turtleDistance == distance){
                    System.out.println("======乌龟赢了==========");
                    flag = false;
                    break;
                }
            }

        }
    }


    public static void main(String[] args) {
        RubbitTurtleRun rubbit = new RubbitTurtleRun();
        RubbitTurtleRun turtle = new RubbitTurtleRun();
        rubbit.setName("兔子");
        turtle.setName("乌龟");

        rubbit.start();
        turtle.start();

    }
}
