首先創(chuàng)建用戶類和機(jī)器類
創(chuàng)建用戶類（User）

public class User {
    String userName;//用戶名
    int score; //得分
    public int userAttribute() {
        System.out.print("請(qǐng)出拳:1.剪刀2.石頭3.布(輸入相應(yīng)的數(shù)字):");
        Scanner scanner = new Scanner(System.in);
        int choice = scanner.nextInt(); //選擇出拳
        switch(choice) {
            case 1:
                System.out.println("你出拳：剪刀");
                break;
            case 2:
                System.out.println("你出拳：石頭");
                break;
            case 3:
                System.out.println("你出拳：布");
                break;
            default:
                System.out.println("輸入錯(cuò)誤!");
                break;
        }
        return choice;  //返回選擇
    }
}
創(chuàng)建機(jī)器人類（Robot）

public class Robot {
    String robotName; //機(jī)器名
    int score;//機(jī)器得分
    public int chuQuan() {
        int random =(int)(Math.random()*3)+1; //生成3個(gè)隨機(jī)數(shù)
        switch(random) {
            case 1:
                System.out.println(computerName+"出拳：石頭");
                break;
            case 2:
                System.out.println(computerName+"出拳：剪刀");
                break;
            case 3:
                System.out.println(computerName+"出拳：布");
                break;
          
        }
        return random;
    }
}
創(chuàng)建管理類(Administrator)

public class Administrator {
    Scanner scanner = new Scanner(System.in);
    User User;//用戶玩家
    Robot Robot;//電腦玩家
    int count;//對(duì)戰(zhàn)次數(shù)

    //游戲類的初始化方法
    public void initial(){
        //創(chuàng)建用戶對(duì)象
        User= new User();
        //創(chuàng)建電腦對(duì)象
        Robot = new Robot();
        //初始化對(duì)戰(zhàn)次數(shù)為0
        count = 0;
    }
    //開始游戲的方法
    public void startGame(){
        System.out.println("*******************");
        System.out.println("**   猜拳洽糟，開始      **");
        System.out.println("*******************");
        System.out.println("出拳規(guī)則：1.石頭 2.剪刀 3.布");
        System.out.println("請(qǐng)輸入你的姓名：");
        User.userName = scanner.next();
        System.out.print("請(qǐng)選著對(duì)方角色(1:劉備 2:孫權(quán) 3:曹操)");
        int choose = scanner.nextInt();//接收用戶選擇的角色
        switch(choose){
            case 1:
                Robot.robotName = "劉備";//把值賦給電腦類的name
                System.out.println("你選擇了"+Robot.robotName+"對(duì)戰(zhàn)");
                break;
            case 2:
                
                Robot.robotName = "孫權(quán)";
                System.out.println("你選擇了"+Robot.robotName+"對(duì)戰(zhàn)");
                break;
            case 3:
                Robot.robotName = "曹操";
                System.out.println("你選擇了"+Robot.robotName+"對(duì)戰(zhàn)");
                break;
            default:
                System.out.println("輸入有誤末贾！");
                break;
        }
        System.out.println("要開始嗎（y/n）");
        String con = scanner.next();
        if(con.equals("n")){//如果不開始輸入"n"的話 就提示退出
            System.out.println("系統(tǒng)退出！");
        }
        int perFist;//用戶出的拳
        int comFist;//計(jì)算機(jī)出的拳
        while(con.equals("y")){
            //出拳
            perFist = User.userAttribute();//調(diào)用用戶類的方法
            comFist = Robot.chuQuan();//調(diào)用電腦類的方法
            //裁決
            if((perFist == 1 && comFist == 1) || (perFist == 2 && comFist == 2) || (perFist == 3 && comFist == 3)){
                System.out.println("結(jié)果：你們平局了");//平局
            }else if((perFist == 1 && comFist == 3) || (perFist == 2 && comFist == 1) || (perFist == 3 && comFist == 2)){
                System.out.println("結(jié)果：你失敗了");
                Robot.score++;//記錄電腦贏的分?jǐn)?shù)
            }else{
                System.out.println("結(jié)果：恭喜，你贏了骡湖！");
                User.score++;//記錄用戶贏的分?jǐn)?shù)
            }
            count++;//對(duì)戰(zhàn)次數(shù)依次加一
            System.out.println("是否進(jìn)入下一輪（y/n）");
            con = scanner.next();
        }
        //如果結(jié)束 則顯示最后的結(jié)果
        showResult();
    }
    //顯示最后的輸出結(jié)果
    public void showResult(){
        System.out.println("****************************************");
        System.out.println(Robot.robotName+"\tVS\t"+User.userName);
        System.out.println("對(duì)戰(zhàn)次數(shù)："+count);
        System.out.println("姓名"+"\t"+"積分");
        System.out.println(User.userName+"\t"+User.score);
        System.out.println(Robot.robotName+"\t"+Robot.score);
        if(User.score>Robot.score){//如果用戶的分?jǐn)?shù)大于電腦的分?jǐn)?shù) 則用戶贏
            System.out.println("恭喜"+User.userName+"贏了廷臼！");
        }else{
            System.out.println("恭喜"+Robot.robotName+"贏了拌蜘！");
        }
        System.out.println("****************************************");
    }
}
最后創(chuàng)建一個(gè)Mian類


public class Mian {
    public static void main(String[] args) {
        Administrator administrator = new Administrator();
        administrator.initial();//調(diào)用初始化方法
        administrator.startGame();//調(diào)用開始游戲的方法
    }
}
