通过实现Runnable接口方式模拟龟兔赛跑。 具体要求如下： 1、100米赛跑，兔子每秒跑2米，乌龟每秒跑1米。 2、兔子在跑过80米的时候，每跑2米休息2秒钟，乌龟每跑1米休息0.1秒。

我们可以使用Java实现一个简单的模拟，首先创建一个`Runner`接口和两个实现了该接口的`Rabbit`和`Turtle`类代表兔子和乌龟。然后，我们可以在`Race`类中维护比赛状态并控制休息时间。以下是模拟的代码：

// 创建Runner接口
interface Runner {
    void startRun();
    void stopRun();
    void rest();
}

// 定义乌龟和兔子的实现类
class Turtle implements Runner {
    private double distance;
    private boolean isRunning = false;

    @Override
    public void startRun() {
        isRunning = true;
        System.out.println("Turtle starts running at 1 meter per second.");
    }

    @Override
    public void stopRun() {
        isRunning = false;
        System.out.println("Turtle stops running.");
    }

    @Override
    public void rest() {
        if (isRunning) {
            double restingTime = distance / 10; // 1m休息0.1秒
            System.out.println("Turtle rests for " + restingTime + " seconds.");
        }
    }

    // 这里可以根据需求添加继续前进的方法
}

class Rabbit implements Runner {
    private double distance, restInterval = 2; // 每跑2米休息2秒

    @Override
    public void startRun() {
        isRunning = true;
        System.out.println("Rabbit starts running at 2 meters per second.");
    }

    @Override
    public void stopRun() {
        isRunning = false;
        System.out.println("Rabbit stops running.");
    }

    @Override
    public void rest() {
        if (isRunning) {
            if (distance % restInterval == 0) {
                double restingTime = restInterval; // 每跑restInterval米休息restInterval秒
                System.out.println("Rabbit rests for " + restingTime + " seconds.");
            }
        }
    }

    // 跑步方法，假设兔子每次增加速度
    public void move(double distance) {
        this.distance += distance;
        rest(); // 先休息再继续跑
    }
}

// 主类 Race
public class Race {
    public static void main(String[] args) {
        int totalDistance = 100;
        double rabbitSpeed = 2, turtleSpeed = 1;
        Rabbit rabbit = new Rabbit();
        Turtle turtle = new Turtle();

        // 同时开始跑步
        rabbit.startRun();
        turtle.startRun();

        // 控制比赛进程
        while (turtle.distance < totalDistance && rabbit.distance < totalDistance) {
            double timeToMove = Math.min(rabbit.distance / rabbitSpeed, turtle.distance / turtleSpeed);
            rabbit.move(timeToMove);
            turtle.move(timeToMove);

            // 根据兔子的休息规则休息
            rabbit.rest();
        }

        // 结束游戏，打印最终成绩
        System.out.println("The race is over! Rabbit wins with a distance of " + rabbit.distance + " meters.");
    }
}
