JavaSE实现猜拳游戏

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) {
