JAVA程序设计(07.2)-----面对对象设计练习 猜拳

1.妥妥的先建立对象

package com.lovo;/** * 类:猜拳游戏~ 暂定3胜制吧~ * @author Abe * *//** * 构造器 *//** * 属性: 1. 石头剪刀布 2. 循环次数 3. 各自胜利次数 */public class Morra {private int finger = 0;private int times = 0;private int pcwin = 0;private int youwin = 0;/** * 动作：电脑获取猜拳 */public void have() {finger = (int) (Math.random() * 3 + 1);}/** * 动作：猜拳转化为数字 1剪刀 2石头 3布 */public int change(String x) {int yours = 3;if (x.equals("剪刀")) {yours = 1;} else if (x.equals("石头")) {yours = 2;}return yours;}/** * 动作：比较输赢 */public String look(int yours) {if (finger == yours) {times++;return "平局~~ 你们玩了" + times + "局了~";} else if (finger == 1 && yours == 3 || finger == 2 && yours == 1|| finger == 3 && yours == 2) {pcwin++;times++;return "哎!这局电脑获胜了~~~你们玩了" + times + "局了~";}youwin++;times++;return "哦!这局你获胜了~~~你们玩了" + times + "局了~";}/** * 调取胜利次数 */public int pcwin() {return pcwin;}public int youwin() {return youwin;}}

然后是主程序

package com.lovo;/** * 猜拳游戏开始~ * @author Abe */import java.util.Scanner;public class Morratest {public static void main(String[] args) {Scanner sc = new Scanner(System.in);Morra pc = new Morra();do {System.out.print("请输入你要猜拳的种类:1石头 2剪刀 3布");int yours = sc.nextInt();pc.have();String hint = pc.look(yours);System.out.println(hint);} while (pc.pcwin() != 3 && pc.youwin() != 3);if (pc.pcwin() == 3) {System.out.println("电脑累计胜利3次~获得了最终胜利。");} else {System.out.println("你累计胜利3次~获得了最终胜利！！");}sc.close();}}

老师的方法~更好的封装~ 有必要还可以加 输赢次数什么的 懒得做了 判断也没做 据说以后会讲 妥妥的~

先是类

package com.lovo;/** * 类:猜拳游戏~ * @author Abe * *//** * 构造器 */public class Morra {public Morra(String str) {this.name = str;}/** * 属性: 1. 石头剪刀布 */private String name = "";private int finger = 0;/** * 动作：电脑获取猜拳 */public void setFinger() {this.finger = (int) (Math.random() * 3 + 1);}/** * 动作：获取玩家输入的猜拳（1~3） */public void setFinger(int x) {this.finger = x;}/** * 动作：猜拳转化为数字 1剪刀 2石头 3布 */public String change(int x) {if (x == 1) {return "1剪刀";} else if (x == 2) {return "2石头";} else {return "3布  ";}}/** * 调取名字,出的什么拳 */public String getName() {return name;}public int getFinger() {return finger;}/** * 判断输赢 并返回字符串 * @param other * @return */public String open(Morra other) {switch (this.getFinger()) {case 1:switch (other.getFinger()) {case 1:return "平局";case 2:return other.getName() + "~ 赢了~~";default:return this.getName() + "~ 赢了~~";}case 2:switch (other.getFinger()) {case 1:return this.getName() + "~ 赢了~~";case 2:return "平局";default:return other.getName() + "~ 赢了~~";}default:switch (other.getFinger()) {case 1:return other.getName() + "~ 赢了~~";case 2:return this.getName() + "~ 赢了~~";default:return "平局";}}}}

程序依旧那么简单~

package com.lovo;/** * 猜拳游戏开始~ * @author Abe */import java.util.Scanner;public class Morratest {public static void main(String[] args) {Scanner sc = new Scanner(System.in);Morra human = new Morra("小和尚");Morra pc = new Morra("法轮");System.out.print("请选择你要出的拳：1剪刀 2石头 3布");human.setFinger(sc.nextInt());System.out.println(human.getName() + "出了"+ human.change(human.getFinger()));pc.setFinger();System.out.println(pc.getName() + "出了" + pc.change(pc.getFinger()));System.out.println(human.open(pc));sc.close();}}
