Java-->簡單的鬥地主發牌流程

package com.dragon.java.hwddz;

import java.util.ArrayList;
import java.util.HashMap;
import java.util.List;
import java.util.Map;

/*1. 寫一個可以給鬥地主三家隨機發牌的程式。   
 a：牌可以隨機發給三個玩家   
 b：在控制台列印每個玩家的牌。   
 c：對每個玩家手中的牌按照大寫排序。
 ```
 牌的花色："♠", "♥", "♣", "♦" 
 *思路：創建一個容器存儲所有的牌，再創建三個容器分別表示三個用戶的牌，三個用戶輪流從第一個容器中取牌，
 *剩下三張為底牌。把大王和小王也算進去**/
public class Test {
    public static void main(String args[]) {
        Map<Integer, String> mapPoker = new HashMap<>();
        List<Integer> listIndex = new ArrayList<>();

        Poker.setPoker(mapPoker, listIndex);

        Poker.washPoker(listIndex);

　　　　　// 定義用戶
        Player[] players = new Player[3];
        players[0] = new Player("躺之徳");
        players[1] = new Player("小剪");
        players[2] = new Player("呆立叫");
　　　　　
　　　　　// 用戶容器
        List<Integer> tzd = new ArrayList<>();
        List<Integer> xj = new ArrayList<>();
        List<Integer> dlj = new ArrayList<>();
        List<Integer> dp = new ArrayList<>();

        Player.getPoker(tzd, xj, dlj, dp, listIndex);

        // int index = Player.getMaxNumber(players);
        // System.out.println(players[index].getName() + "搶到了地主！");

        players[0].showPoker(tzd, mapPoker);
        players[1].showPoker(xj, mapPoker);
        players[2].showPoker(dlj, mapPoker);
        // players[index].showDp(dp, mapPoker);

        System.out.println("\n" + "底牌：");
        for (Integer integer : dp) {
            System.out.print(mapPoker.get(integer) + "   ");
        }
    }
}

--> Poker類用於存入54張撲克牌

package com.dragon.java.hwddz;

import java.util.Collections;
import java.util.List;
import java.util.Map;

public class Poker {
    private static String[] pokerColor = { "♠", "♥", "♣", "♦" };
    private static String[] pokerNum = { "3", "4", "5", "6", "7", "8", "9",
            "10", "J", "Q", "K", "A", "2" };
　　
　　 // 存入54張不同的牌，並給每張牌一個標號
    public static void setPoker(Map<Integer, String> mapPoker,
            List<Integer> listIndex) {
        int index = 0;
        for (String nums : pokerNum) {
            for (String colors : pokerColor) {
                String poker = colors.concat(nums);
                mapPoker.put(index, poker);
                listIndex.add(index);
                index++;
            }
        }
        mapPoker.put(index, "大☝王");
        listIndex.add(index);
        index++;
        mapPoker.put(index, "小☟王");
        listIndex.add(index);
    }

　　 // 洗牌 --> 即洗標號
    public static void washPoker(List<Integer> listIndex) {
        Collections.shuffle(listIndex);
    }

}

--> Player類對玩家進行發牌和顯示處理（寫完我就後悔了，J,Q,K,A,2的排序太low了..package com.dragon.java.hwddz;
