猜拳游戏 java基础

//用循环方式实现和计算机玩猜拳的程序 (设定胜出条件--输3次或赢3次即退出)

package eduask01;

import java.util.*;

public class Rask03 {

public static void main(String[]args){

Scanner sc=new Scanner(System.in);

int m=0,n=0;//累计输或赢的次数

for(;;){//死循环进行游戏

System.out.println("猜拳游戏：1.表示石头 2.表示剪刀3.表示布.请输入一个数字猜拳");

int num=sc.nextInt();//自己猜的拳

int Num=(int)(Math.random()*3+1);//电脑随机出的拳

switch(num){//自己的3种情况 并分别说明

  case 1:

  System.out.println("你出的是石头：");break;

  case 2:

  System.out.println("你出的是剪刀：");break;

  case 3:

  System.out.println("你出的是布：");break;  

}switch (Num){//电脑的3中情况

case 1:

System.out.println("电脑的是石头：");break;

  case 2:

  System.out.println("电脑出的是剪刀：");break;

  case 3:

  System.out.println("电脑出的是布：");break;

}

if (num==Num){//判定平局

System.out.println("-_-平局");

}else if(num==1&&Num==2||num==2&&Num==3||num==3&&Num==1){//判定获胜

System.out.println("^-^恭喜你胜利了"); m+=1;

}else {System.out.println("o-o很遗憾 你输了"); n+=1;}//其他就是指输的情况

    if (m==3){System.out.println("你已经赢了3局 已经退出猜拳游戏");break;}//赢了3次

    else if(n==3){System.out.println("电脑已经赢了3次 你已经退出猜拳游戏");break;}//输了3次
