先有一個(gè)人(Person)
有一個(gè)電腦(Computer)和人玩
有一個(gè)控制器,為人和電腦玩提供方法
一個(gè)測(cè)試類:用來使用控制器

Person類

package checGame;

import java.util.Scanner;

public class Person {
    String name;
    int score;

    // 規(guī)定 1:石頭2:剪刀 3:包子
    int play() {
        System.out.println("請(qǐng)出拳:(1:石頭2:剪刀3:布)");
        Scanner sc = new Scanner(System.in);
        int num = sc.nextInt();
        switch (num) {
        case 1: {
            System.out.println(this.name + "出拳");
            break;
        }
        case 2: {
            System.out.println(this.name + "出剪刀");
            break;
        }
        default: {
            System.out.println(this.name + "出布");
            break;
        }
        }
        return num;
    }

    public Person() {

    }

    public Person(int score) {
        this.score = score;

    }

}
##Computer類
package checGame;

import java.util.Random;

public class Computer {
    String name;
    int score;
    
    //出拳
    int play(){
        Random rand = new Random();
        //1:石頭 2:剪刀 3:布
        int num = rand.nextInt(3)+1;
        switch (num) {
        case 1:{
            System.out.println(this.name + "出拳");
            break;
            }
        case 2:{
            System.out.println(this.name+"出剪刀");
            break;
            }
        default:{
            System.out.println(this.name+"出布");
            break;
            }
        }
        return num;
    }


    //默認(rèn)構(gòu)造方法
    public Computer () {
        
    }
    //重寫構(gòu)造方法,一定要把默認(rèn)的寫出來
    public Computer(int score) {
        this.score = score;
    }

}

Menu類

package checGame;

import java.util.Scanner;

public class Menu {
    Computer roboat;
    Person person ;
    //初始化游戲
    //構(gòu)造方法
    public Menu(){
        
    }
    
    void init(){
    //創(chuàng)建一個(gè)機(jī)器對(duì)象
    this.roboat = new Computer(0);
    System.out.println("請(qǐng)輸入電腦的名字");
    Scanner sc = new Scanner(System.in);
    this.roboat.name = sc.next();
    
    
    
    //創(chuàng)建一個(gè)人對(duì)象
    this.person = new Person(0);
    System.out.println("請(qǐng)輸入你的名字");
    this.person.name = sc.next();
    }
    //開始游戲
    void start(){
        //人先出拳
        int num = this.person.play();
        //機(jī)器出拳
        int num1 = this.roboat.play();
        //計(jì)算分?jǐn)?shù)
        this.calculate(num, num1);
        System.out.println("游戲是否結(jié)束(exit)");
        Scanner sc = new Scanner(System.in);
        if ("exit".equals(sc.next())) {
            //展示分?jǐn)?shù)
            show();
            return;
        }else {
            start();
        }
    }
    //計(jì)算分?jǐn)?shù)
    //num :人出拳的值 num1:機(jī)器出拳的值
    void calculate(int num ,int num1){
        if (num == num1) {
            //平局
            System.out.println("平局");
            return;
        }
        if ((num==1&&num1==2)||(num==2&&num1==3)||(num==3&&num1==1)) {
            //人勝利
            System.out.println("人勝利");
            this.person.score++;
        }else{
            //機(jī)器勝利
            System.out.println("機(jī)器勝利");
            this.roboat.score++;
        }
    }


    //展示分?jǐn)?shù)
    void show(){
        System.out.println(this.person.name+"得分" +this.person.score);
        System.out.println(this.roboat.name+"得分" +this.roboat.score);
    }

}
