本文实例为大家分享了java实现猜拳小游戏的具体代码，供大家参考，具体内容如下

User.java


import java.util.Scanner;
public class User {
    String name;
    int score;
    public int showFist(){
        System.out.println ("请出拳：1.剪刀\t2.石头\t3.布");
        Scanner input=new Scanner ( System.in );
        int choice=input.nextInt ();
        if(choice==1){
            System.out.println ("您出了剪刀");
        }else if(choice==2){
            System.out.println ("您出了石头");
        }else if (choice==3){
            System.out.println ("您出了布");
        }else {
            System.out.println ("输入有误！");
        }
        return choice;
    }
}

Computer.java


public class Computer {
    String name;
    int score;
    public int showFist () {
        int choice = (int) (Math.random () * 3) + 1;    //产生随机数
        if (choice == 1) {
            System.out.println (name +"出了剪刀" );
        } else if (choice == 2) {
            System.out.println (name +"出了石头" );
        } else if (choice == 3) {
            System.out.println (name +"您出了布" );
        } else {
            System.out.println ( "输入有误！" );
        }
        return choice;
    }
}

Game.java
