Posted 2021-01-12 xiao-ran

第一个类，玩家类：

import java.util.Scanner;
/**
 * 创建玩家类
 */
public class Person {
    Scanner input = new Scanner(System.in);
    /**
     * 定义玩家类的属性
     */
    String name;
    int score;
    String action;
    int num;
    /**
     * 定义玩家类的猜拳方法
     */
    public void method() {
        System.out.println("
请出拳：1.剪刀 2.石头 3.布");
        boolean a = true;
        do {

            num = input.nextInt();
            if (num == 1 || num == 2 || num == 3) {
                switch (num) {
                case 1:
                    action = "剪刀";
                    break;
                case 2:
                    action = "石头";
                    break;
                case 3:
                    action = "布";
                    break;
                }
                a = false;
                System.out.println("你出拳：" + action);
            } else {
                System.out.println("输入数字有误,请重新输入");
            }

        } while (a);
    }
}

第二个类，电脑类：

    /**
     * 电脑类
     */
public class Computer {
        /**
     * 定义电脑类的属性
     */
    String name;
    int score;
    String action;
    int num;
        /**
     * 定义电脑类的猜拳方法
     */
    public void method(){
            /**
            *随机产生数字123
            */
        num=(int)((Math.random())*3)+1;
        switch(num){
        case 1:
            action="剪刀";
            break;
        case 2:
            action="石头";
            break;
        case 3:
            action="布";
            break;
        }
        System.out.println(name+"出拳："+action);
        
    }
}
                                    

第三个类，游戏类：

import java.util.Scanner;

 * 游戏类
 */
public class Game {
    Scanner input = new Scanner(System.in);

     * 定义游戏类的属性
     */

    int number;
    int frequency = 0;
    /**
     * 定义游戏进程的方法
     */
    public void process() {
        System.out
                .println("--------------------------欢迎进入游戏世界--------------------------

        System.out.println("		********************************");
        System.out.println("		**********猜拳，开始*************");
        System.out.println("		********************************");

        System.out.print("请选择对方角色（1:刘备2:孙权3:曹操）:");
        boolean b = true;
        do {

            if (number == 1 || number == 2 || number == 3) {
                switch (number) {
                case 1:

        person.name = input.next();
        System.out.println(person.name + "  VS  " + computer.name + "  对战
");
        System.out.println("要开始吗？(y/n)");
        char answer = input.next().charAt(0);
        while (answer == ‘y‘) {
            person.method();
            computer.method();
            if (person.num == computer.num) {
                System.out.println("嘿嘿，和局，等着瞧吧！");
            } else if (((person.num == 2) && (computer.num == 1))

            answer = input.next().charAt(0);
        }
    }
    /**
     * 定义游戏结算的方法
     */
    public void showResult() {
        System.out.println("********************************");
        System.out.println(person.name + "  VS  " + computer.name);
        System.out.println("对战次数：" + frequency);
        System.out.println("
姓名		得分");

        } else {
            System.out.println("哇，你好棒啊！");
        }
        System.out.println("********************************");

    }
}

测试类：

public class Demo {
public static void main(String[] args) {
    Game play=new Game();//创建游戏类的对象
    play.process();//调用游戏类的游戏进程方法
    play.showResult();//调用游戏类的结算方法
}
}
