猜拳游戏之面向对象

本文主要是介绍猜拳游戏之面向对象，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

猜拳游戏

要求：用户可以选择对战的角色名称（1,刘备 2,关羽 3,张飞），也可以自由输入自己名称，在对战期间，电脑由系统随机出拳（1，剪刀 2，石头 3， 布），玩家由自己出拳，结束后可以看到自己和电脑的手势，以及得分情况，（赢一局积3分，输一局不扣分，平局各加一分）。在整局游戏结束后要求显示出胜负情况以及积分情况。

类的设计

本局游戏设置为四个类分别是玩家类、电脑类、裁判类、游戏测试类。

玩家类

属性：昵称（roleName）积分（integral）

方法：玩家出拳（printMora）

电脑类

属性：名称（roleName）积分（integral）

方法：电脑出拳（printMora）

裁判类

属性：玩家（player）电脑（computer）局数（gameNumber）

方法： 游戏开始准备（start()） 猜拳输赢判定（arbitrament()） 游戏结果公示（end()）游戏过程（wholeJourney()）转换手势（changeString(int mora, Object gamePlayer)）

代码展示

玩家类

package com.qianfeng.moraGame;import java.util.Scanner;//玩家类
public class Player {private String roleName;//玩家姓名private int integral;//玩家积分public Player() {}public Player(String roleName, int integral) {this.roleName = roleName;this.integral = integral;}//玩家猜拳public int printMora() {Scanner input = new Scanner(System.in);int mora = input.nextInt();
//		input.close();return mora;}public String getRoleName() {return roleName;}public void setRoleName(String roleName) {this.roleName = roleName;}public int getIntegral() {return integral;}public void setIntegral(int integral) {this.integral = integral;}}

电脑类

package com.qianfeng.moraGame;import java.util.Random;//电脑类
public class Computer {private String roleName;//电脑名字private int integral;//电脑积分public Computer() {}public Computer(String roleName, int integral) {this.roleName = roleName;this.integral = integral;}//电脑猜拳public int printMora() {Random random = new Random();int mora = random.nextInt(3)+1;return mora;}public void setRoleName(String roleName) {this.roleName = roleName;}public String getRoleName() {return this.roleName;}public void setIntegral(int integral) {this.integral = integral;}public int getIntegral() {return integral;}}

裁判类

package com.qianfeng.moraGame;import java.util.Scanner;//裁判类
public class Referee {Scanner input = new Scanner(System.in);private Player player;private Computer computer;private int gameNumber;public Referee() {}public Referee(Player player, Computer computer) {this.player = player;this.computer = computer;}//游戏开始准备private void start() {System.out.println("***************************");System.out.println("*      欢迎您进入游戏          *");System.out.println("***************************");int n;do {System.out.print("请选择您对战的角色（1,刘备 2,关羽 3,张飞）：");n = input.nextInt();if (n == 1 || n == 2 || n == 3) {break;} else {System.out.println("输入错误！！");}} while (true);switch (n) {case 1:computer.setRoleName("刘备");break;case 2:computer.setRoleName("关羽");break;case 3:computer.setRoleName("张飞");break;}System.out.print("请输入您的游戏昵称：");player.setRoleName(input.next());System.out.println(player.getRoleName() + " VS " + computer.getRoleName());System.out.println();}//猜拳输赢判定private void arbitrament() {int mora1;do {System.out.print("请" + player.getRoleName() + "出拳（1,剪刀 2,石头 3,布）：");mora1 = player.printMora();if (mora1 == 1 || mora1 == 2 || mora1 == 3) {break;} else {System.out.println("输入错误！！");}} while (true);int mora2 = computer.printMora();System.out.println(computer.getRoleName() + "由系统出拳完毕");changeString(mora1, player);changeString(mora2, computer);if (mora1-mora2 == 1 || mora1-mora2 == -1) {System.out.println("恭喜您取得一局胜利加3积分");player.setIntegral(player.getIntegral()+3);} else if (mora1-mora2 == -1 || mora1-mora2 == 2) {System.out.println("您惜败" + computer.getRoleName() + "加3积分");computer.setIntegral(computer.getIntegral()+3);} else {System.out.println("平手各加一积分");player.setIntegral(player.getIntegral()+1);computer.setIntegral(computer.getIntegral()+1);}}//游戏结束公示private void end() {System.out.println();System.out.println("公布此次游戏的最终结果：\n结果场次为：" + gameNumber);System.out.println(player.getRoleName() + "积分为：" + player.getIntegral());System.out.println(computer.getRoleName() + "积分为：" + computer.getIntegral());if (computer.getIntegral() < player.getIntegral()) {System.out.println("恭喜您此次游戏您胜利了！！！");} else if(computer.getIntegral() > player.getIntegral()) {System.out.println("很遗憾此次游戏您惜败！！！");} else {System.out.println("平分秋色！！！");}System.out.println("游戏结束");}//游戏过程public void wholeJourney() {start();String judge;do {arbitrament();System.out.println();System.out.print("是否继续战斗（y/n）：");judge = input.next();gameNumber++;} while (judge.equals("y"));end();}//转化手势private void changeString(int mora, Object gamePlayer) {String name;if(gamePlayer instanceof Player) {Player player = (Player)gamePlayer;name = player.getRoleName();} else if (gamePlayer instanceof Computer) {Computer computer = (Computer)gamePlayer;name = computer.getRoleName();} else {name = "错误昵称";}switch (mora) {case 1:System.out.println(name + "出拳为：剪刀");break;case 2:System.out.println(name + "出拳为：石头");break;case 3:System.out.println(name + "出拳为：布");break;}}public int getGameNumber() {return gameNumber;}public void setGameNumber(int gameNumber) {this.gameNumber = gameNumber;}}

游戏测试类

package com.qianfeng.moraGame;import java.util.Scanner;public class GameTest {public static void main(String[] args) {Scanner input = new Scanner(System.in);Player player = new Player();Computer computer = new Computer();Referee referee = new Referee(player,computer);String judge;do {referee.wholeJourney();System.out.print("是否继续一局新的游戏（y/n）：");judge = input.next();System.out.println();//新的一局初始积分与局数referee.setGameNumber(0);player.setIntegral(0);computer.setIntegral(0);} while (judge.equals("y"));System.out.println("欢迎下次再来");input.close();}
}
