Java-斗地主小游戏洗牌发牌(控制台程序)

一分析:

1:创建扑克牌
CreatePlayingCards();
2:洗牌
AntomaticLicensing();
3:给三名玩家进行发牌
DealCards();
采用集合:
HashMap<Integer,String>map;
ArrayListcards

相关API信息:
Collections.shuffle(cards);
-

Collections.sort(user);
-

二:代码详情

import java.util.Collections;
import java.util.HashMap;
public class PlayingCard {
     //创建扑克牌
      private static HashMap<Integer,String>map;

               //洗牌
               AntomaticLicensing();
               //给三名玩家进行发牌,并打印发牌情况
             DealCards();
            }
           
           //【1】创建扑克牌
           private static void CreatePlayingCards(){
               //定义花色和数字
               String [] color={"♠","♥","♣","♦"};

          //【2】洗牌
           private static void AntomaticLicensing() {
               //定义一个集合，用来表示一副54张牌的编号，ArrayList里边为0-53的数的编号
                cards=new ArrayList<Integer>();
                 for(int i=0;i<=53;i++){

                 }
                 //洗牌，使用Collections工具类的Shuffle()类
                 Collections.shuffle(cards);
              }
           
         //【3】给三名玩家发牌,并打印发牌情况

               //创建三个玩家和底牌
               ArrayList<Integer>iplayer1=new ArrayList<Integer>();

               //遍历这幅洗好的牌，遍历过程中，将牌发到三个玩家和底牌中
               //这里采用的算法是 底牌>=51的数字  小王:i%3==0  小强:i%3==1 卢本伟:除了上面情况之外的牌
               for (int i = 0; i < cards.size(); i++) {
                      if (i>=51) {
                       iSecretCards.add(cards.get(i));
                    }else if (i%3==0) {
                        //与3取余为0的发给玩家1
                        iplayer1.add(cards.get(i));

                    }     
                 }
                //打印最后结果
                 System.out.print("小王:");
                 Ponint(iplayer1);
                System.out.print("小强:");

                 Ponint(iplayer3);
                System.out.print("底牌:");
                 Ponint(iSecretCards);
            }
         //打印
         public static void Ponint(ArrayList<Integer> user){
             Collections.sort(user);
