今天看了前三章，作为一个初学者，感觉这本书还是很让我感兴趣的，它里面的一些插画和游戏，能让你学起来没那么枯燥。

自己尝试着把里面一个较为简单的游戏写了一遍。

游戏设计到game和player两个对象。game会产生介于0~9之间的随机数字，3个player对象会猜测该数字，1个player猜到就结束游戏。

package study;

public class Count {

   //用三个实例对象表示三个player对象
   Player p1;
   Player p2;
   Player p3;

   public void StartGame() {

       //创建出player对象
       p1 = new Player();
       p2 = new Player();
       p3 = new Player();

       //给他们猜测的值赋为0
       int guessp1 = 0;
       int guessp2 = 0;
       int guessp3 = 0;

       //用来判断是否猜测正确
       boolean P1guess = false;
       boolean P2guess = false;
       boolean P3guess = false;

       //随机生成0~9的整数
       int random1 = (int) (Math.random()*10);

       while(true) {
           System.out.println("number is "+random1);

           //调用guess方法
           p1.guess();
           p2.guess();
           p3.guess();

           //guess方法中的值赋给player对象
           guessp1 = p1.number;
           System.out.println("p1 guess number is "+guessp1);

guessp2 = p2.number;
System.out.println("p2 guess number is "+guessp2);

guessp3 = p3.number;
System.out.println("p3 guess number is "+guessp3);

           //判断猜测的数值与随机数值是否相同
           if(guessp1 == random1) {
               P1guess = true;
           }

           if(guessp2 == random1) {
               P2guess = true;
           }

           if(guessp3 == random1) {
               P3guess = true;
           }

           //如果有一个或多个猜中，就打印结果并结束
           if(P1guess || P2guess || P3guess) {
               System.out.println("player win the game");
               System.out.println("p1 win the game? "+P1guess);
               System.out.println("p2 win the game? "+P2guess);
               System.out.println("p3 win the game? "+P3guess);
               System.out.println("game over");
               break;
           }else {//否则继续游戏
               System.out.println("you lose");
           }
       }
   }

   //主方法，开始游戏
   public static void main(String[] args) {
       Count game = new Count();
       game.StartGame();
       }
}

    //创建player类
    class Player {

       int number = 0;

       //随机生成player猜测的数
       public void guess() {
       number = (int) (Math.random()*10);
       System.out.println("i guess number is "+ number);
   }
}
