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

import java.util.Random;import java.util.Scanner;public class CaiQuan { private String userName;//存储用户名 private String cName;//存储对手 private int cNameNum;//存储玩家选择的对手代号 private String userInfo;//用户出拳信息 private String cInfo;//电脑出拳信息 private int uNum;//接收用户输入的数 private int cNum;//接受电脑产生的数 private Scanner sc; private static final String Army01 = "张飞"; private static final String Army02 = "关羽"; private static final String Army03 ="刘备"; private static boolean flag ;//平局和电脑胜为true,玩家赢为fasle private int selectInfo;//玩家是否继续游戏，1表示继续，0表示结束 private int score = 0;//分数 public static void main(String[] args) { CaiQuan cq = new CaiQuan(); cq.gameInfo(); do{ cq.selectArmy(); cq.userInput(); cq.cOutput(); cq.compareCaiQuan(); cq.gameOver(); }while(flag); } public CaiQuan(){ } //打印游戏信息 public void gameInfo(){ System.out.println("欢迎进行猜拳小游戏！"); System.out.println("1.表示石头 2.表示剪刀 3.表示布"); sc = new Scanner(System.in); if(userName==null){ System.out.println("玩家请输入用户名："); System.out.println("============================================="); userName = sc.next(); } } //选择对手 public void selectArmy(){ System.out.println("============================================="); System.out.println("对手选择列表："); System.out.println("1："+Army01+" 2："+Army02+" 3："+Army03); System.out.println(userName+"请输入对手:"); System.out.println("============================================="); test01(); System.out.println(userName+",您选择的对手为"+cName); System.out.println("============================================="); } //判断对手 public void test01(){ cNameNum = sc.nextInt(); if(cNameNum==1){ cName = Army01; }else if(cNameNum==2){ cName = Army02; }else if(cNameNum==3){ cName = Army03; }else{ System.out.println("对手选择错误，请重新选择！"); test01(); } } //开始游戏 public void userInput(){ System.out.println(userName+"请出拳:"); System.out.println("1.表示石头 2.表示剪刀 3.表示布"); System.out.println("============================================="); test(); System.out.println("============================================="); System.out.println(userName+"的出拳为："+userInfo); } //判断输入的数是否错误 public void test(){ uNum = sc.nextInt(); if(uNum==1){ userInfo = "石头"; }else if(uNum==2){ userInfo = "剪刀"; }else if(uNum==3){ userInfo = "布"; }else{ System.out.println("输入错误，请请重新输入"); test(); } } //电脑出拳 public void cOutput(){ Random random = new Random(); cNum = random.nextInt(3)+1; if(cNum==1){ cInfo = "石头"; }else if(cNum==2){ cInfo = "剪刀"; }else if(cNum==3){ cInfo = "布"; } System.out.println(cName+"出拳为:"+cInfo); } //比较大小 public void compareCaiQuan(){ String msg = null; if(uNum == 1){ if(cNum == 1){ msg="此时平局"; flag = true; }else if(cNum == 2){ score += 1; msg="此时"+userName+"胜出"; flag = false; }else { score -= 1; msg="此时"+cName+"胜出"; flag = true; } return; }else if(uNum == 2){ if(cNum == 1){ score -= 1; msg="此时"+cName+"胜出"; flag = true; }else if(cNum == 2){ msg="此时平局"; flag = true; }else { score += 1; msg="此时"+userName+"胜出"; flag = false; } }else { if(cNum == 1){ score += 1; msg="此时"+userName+"胜出"; flag = false; }else if(cNum == 2){ score -= 1; msg="此时"+cName+"胜出"; flag = true; }else { msg=" 此时平局"; flag = true; } } System.out.println(msg); } //游戏结束信息 public void gameOver(){ System.out.println("============================================="); if(flag==true){ System.out.println(userName+",您没有战胜电脑,不要灰心，请继续游戏!"); System.out.println("============================================="); System.out.println("继续游戏请输入：1 结束游戏请输入：2"); test02(); }else if(flag==false){ System.out.println(userName+",您太厉害了,竟然战胜了"+cName+"，游戏结束！"); System.out.println("============================================="); System.out.println("继续游戏请输入：1 结束游戏请输入：2"); test02(); } } //判断玩家是否继续游戏 public void test02(){ selectInfo = sc.nextInt(); if(selectInfo==1){ flag = true; }else if(selectInfo==2){ System.out.println(userName+",您的游戏分数为："+score); System.exit(0); }else{ System.out.println(userName+"，您输入错误，请重新输入！"); test02(); } }}
