JAVA 猜拳游戏

JAVA 猜拳游戏

题目:通过控制台方式实现一个人机对战的猜拳游戏

用户通过输入(0.石头子 1.剪刀 2.布),机器随机生成(0.石头子 1.剪刀 2.布)

要求:

  1. 能打印玩家的对局信息,胜利的次数,平局次数,和平局次数
package HomeWorkExercise;

import java.util.Iterator;
import java.util.Random;
import java.util.Scanner;

public class Homework14 {
	public static void main(String args[]) {
		String name = "小杨";
		Game game = new Game(name);
		
		//进行10次猜拳
		for(int i = 1 ; i <= 5 ; i++) {
			
			game.play();
			System.out.println();
		}
		
		//打印情况
		game.getInfo();
		
	}
}


/*
 * 思路
 * 0 石头 1剪刀 2布
 * 1.电脑端:生成一个随机数 并返回,0~2
 * 2.玩家:用户输入,0~2,超出范围提示输入错误,并重新输入
 * 3.进行猜拳游戏
 *   进行枚举
 *   电脑端 0 
 *   	玩家出2 算赢,0算平局,1算输
 *   电脑端 1
 *   	玩家出0 算赢,1算平局,2算输
 *   电脑端 2
 *   	玩家出1 算赢,2算平局,0算输
