Java作业 第十三章 人机猜拳

人机猜拳:
人机类Computer代码:

import java.util.Scanner;
public class Computer {
	String name = "电脑";// 名字
	int score = 0;// 积分
	public int showFist() {
        //产生随机数
        int show = (int) ((Math.random()*10)%3+1); // 产生随机数,表示电脑出拳
        //输出出拳结果并返回
        switch (show) {
        case 1:
            System.out.println(name+"出拳：剪刀");
            break;
        case 2:
            System.out.println(name+"出拳：石头");
            break;
        case 3:
            System.out.println(name+"出拳：布");
            break;
        }

        return show;
    }
}

用户类Person:

import java.util.*;
public class Person {
	String name = "匿名"; //名字
    int score = 0;      //积分    

    public int showFist(){
        //接收用户的选择
        Scanner input = new Scanner(System.in);
        System.out.print("\n请出拳(1.剪刀2.石头3.布):");
        int show = input.nextInt();
        //输出出拳结果，并且返回
        switch (show) {
        case 1:
            System.out.println("你出拳：剪刀");
            break;
        case 2:
            System.out.println("你出拳：石头");
            break;
        case 3:
            System.out.println("你出拳：布");
            break;
        }
        return show;
    }

}

游戏类核心Game:

import java.util.*;
public class Game {
	Person person ; //用户

    Computer computer;//人机
    int count;// 对战次数

    public void inital(){
        person = new Person();
        computer = new Computer();
        count = 0;
    }
    //开始游戏
    public void startGame(){
        System.out.println("-------------欢迎进入猜拳游戏---------------");
        System.out.println();
        System.out.println("******************************************");
        System.out.println("          **  猜拳，开始  **");
        System.out.println("******************************************");
        System.out.println();
        System.out.println("出拳规则：1.剪刀2.石头3.布");
        Scanner input = new Scanner(System.in);
        String exit="n";//退出系统
        do {
            inital();//初始化
            //选择对手
            System.out.print("选择你的对手(1.刘备2.孙权3.曹操):");
            int role = input.nextInt();

测试类Test:

package class3;

public class Test {

	public static void main(String[] args) {
		// TODO Auto-generated method stub
		
		        Game game = new Game();

		        game.inital();

		        game.startGame();
	}
