Java扑克牌游戏-优快云博客

本Java程序实现了创建一副标准扑克牌并进行洗牌、发牌的过程。程序首先定义了花色和数字，然后创建了每张牌的对应关系，并加入了大小王。接着通过洗牌算法随机分配牌给三个玩家，并保留两张底牌。

import java.util.ArrayList;
import java.util.Collections;
import java.util.HashMap;
import java.util.List;
public class Cards {
public static void main(String[] args)
{
  //创建花色
  ArrayList<String> color = new ArrayList<String>();
  color.add("♠");
  color.add("♥");
  color.add("♦");
  color.add("♣");

  //创建牌的大小
  ArrayList<String> number = new ArrayList<String>();

  //添加Collections方法
  Collections.addAll(number, "3","4","5","6","7","8","9","10","J","Q","K","A","2");

  //创建1-54牌的对应关系
  HashMap<Integer,String> map = new HashMap<Integer,String> ();

  int index = 0;
  for(String thisnumber:number)
  {
   for(String thiscolor:color)
   {
     map.put(index++,thisnumber+thiscolor);
   }
  }

  map.put(index++,"Joker1");
  map.put(index++,"Joker2");

  //创建key的集合
  ArrayList<Integer> cards = new ArrayList<Integer>();
  for(int i = 0; i <= 53; i++)
  {
   cards.add(i);
  }
  //洗牌
  Collections.shuffle(cards);
  //发牌
  ArrayList<Integer> iPlayer1 = new ArrayList<Integer>();
  ArrayList<Integer> iPlayer2 = new ArrayList<Integer>();
  ArrayList<Integer> iPlayer3 = new ArrayList<Integer>();
  ArrayList<Integer> iCards = new ArrayList<Integer>();
  for (int i = 0; i < cards.size(); i++) {
   if(i>=51) {
    iCards.add(cards.get(i));
   } else {
    if(i%3==0) {
     iPlayer1.add(cards.get(i));
    }else if(i%3==1) {
     iPlayer2.add(cards.get(i));
    }else {
     iPlayer3.add(cards.get(i));
    }
   }
  }

  Collections.sort(iPlayer1);
  Collections.sort(iPlayer2);
  Collections.sort(iPlayer3);
  //根据key 找值
  ArrayList<String> sPlayer = new ArrayList<String>();
  ArrayList<String> sPlayer2 = new ArrayList<String>();
  ArrayList<String> sPlayer3 = new ArrayList<String>();
  ArrayList<String> sCards = new ArrayList<String>();

  for(Integer key:iPlayer1)
  {
   sPlayer.add(map.get(key));
  }
  for (Integer key : iPlayer2) {
   sPlayer2.add(map.get(key));
  }
  for (Integer key : iPlayer3) {
   sPlayer3.add(map.get(key));
  }
  for (Integer key : iCards) {
   sCards.add(map.get(key));
  }
  //展示
  System.out.println(sPlayer);
  System.out.println(sPlayer2);
  System.out.println(sPlayer3);
  System.out.println(sCards);

  }

}
