# 二、Java面向对象之猜拳游戏 #

## 2.1 要求 ##

与电脑进行猜拳并记录分数。

## 2.2 Computer.java 源代码(电脑自动随机出拳) ##

public class Computer { 
        public void Fingers(int index) { 
            String[] fingers = { "石头", "剪刀", "布"};
            System.out.println("电脑出拳：" + fingers[index]);
        }
    }

## 2.3 Game.java 源代码(实现主要功能的类) ##

import java.util.Random;
    import java.util.Scanner;
    
    public class Game { 
        public void initial(){ 
            //页面
            Scanner scanner = new Scanner(System.in);
            System.out.println("-------------------欢迎进入游戏界面-------------------");
            System.out.println();
            System.out.println(" ***********************");
            System.out.println(" *******猜拳，开始！******");
            System.out.println(" ***********************");
            System.out.println("出拳规则：0.石头 1.剪刀 2.布");
    
            //输入姓名
            System.out.print("请输入你的姓名：");
            String name = scanner.next();
            System.out.println(name+" VS 汶老板 对战");
    
            //判断是否开始
            System.out.print("要开始吗？（输入yes/no）:");
            String b =scanner.next();
            int count = 0;
            int usercount=0;
            int computercount=0;
            while (b.equals("yes")){ 
                //统计对战次数
                count++;
    
                //玩家出拳
                System.out.print("请出拳 0.石头 1.剪刀 2.布（输入相对应的数字）：");
                int a = scanner.nextInt();
                String [] fingers = { "石头","剪刀","布"};
                System.out.println("你出拳："+fingers[a]);
    
                //电脑随机出拳
                Random random = new Random();
                int index = random.nextInt(3);
                Computer computer = new Computer();
                computer.Fingers(index);
    
                //判断输赢
                if ((a == 0 && index == 1)||(a == 1 && index == 2)||(a == 2 && index == 0)) { 
                    System.out.println("结果说：恭喜你，你赢得了！");
                    usercount = usercount+1;
                }else if ((a == 0 && index == 2)||(a == 1 && index == 0)||(a == 2 && index == 1)){ 
                    System.out.println("结果说：很抱歉，你输了！");
                    computercount = computercount+1;
                }else{ 
                    System.out.println("结果说：平局！");
                }
    
                //是否进行下一局
                System.out.print("是否继续进行下一局！（输入yes/no）");
                b = scanner.next();
            }
    
            //总结
            System.out.println("----------------------总结---------------------");
            System.out.println(name+" VS 汶老板");
            System.out.println("对战次数："+count);
            System.out.println("姓名\t\t得分");
            System.out.println("汶老板\t"+computercount);
            System.out.println(name+"\t"+usercount);
            String i = computercount>usercount?"很遗憾，你输了本场比赛！":computercount<usercount?"恭喜你，你赢得了本场比赛！":"平局！";
            System.out.println(i);
        }
    }

## 2.3 Client.java 源代码(测试类) ##

public class Client { 
        public static void main(String[] args) { 
            Game game  = new Game();
            game.initial();
        }
    }

## 2.4 结果截图 ##
