Java实现斗地主的发牌功能 Java实现斗地主的发牌功能

斗地主是全国范围内的一种桌面游戏，尽管全国各种类型，但大同小异，今天我们先来实现一下斗地主中的发牌功能，为了程序的可读性以及可拓展性，此次我们使用面向对象的方法来实现此功能。
首先，斗地主要求有扑克和玩家才能开始游戏，所以这里我们首先要创建一个扑克牌实体类和一个玩家实体类，具体代码如下：
首先是Poker类，含点数，花色和排序属性，大小王之后额外添加，这里我们必须实现一个Comparable接口，方便之后进行排序：

public class Poker implements Comparable{ private String flower; private String pointer; private int sort; public Poker() { } public Poker(String flower, String pointer, int sort) {super(); this.flower = flower; this.pointer = pointer; this.sort = sort; } public String getFlower() {return flower; } public void setFlower(String flower) {this.flower = flower; } public String getPointer() {return pointer; } public void setPointer(String pointer) {this.pointer = pointer; } public int getSort() {return sort; } public void setSort(int sort) {this.sort = sort; } @Override public String toString() {return flower +"-" + pointer; } @Override public int compareTo(Poker a) {return this.getSort() - a.getSort(); } }

【Java实现斗地主的发牌功能】然后就是Player类，这里我们定义属性有id，玩家名字以及玩家手牌和是否地主：

import java.util.ArrayList; public class Player { private int id; private String name; private ArrayList pokers = new ArrayList<>(); private boolean boss; public Player() { } public Player(int id, String name) {super(); this.id = id; this.name = name; } public int getId() {return id; } public void setId(int id) {this.id = id; } public String getName() {return name; } public void setName(String name) {this.name = name; } public ArrayList getPokers() {return pokers; } public void setPokers(ArrayList pokers) {this.pokers = pokers; } public boolean isBoss() {return boss; } public void setBoss(boolean boss) {this.boss = boss; }}

实体类建完之后，我们就要开始实现功能了，首先我们将要实现的功能简单叙述一下，首先我们要求有一副54张的完整牌，然后洗牌（此处我们用Collections里的静态shuffle方法实现），然后开始按洗好的牌发牌51张，发完随机地主，将剩余的三张牌给地主，并将三名玩家的牌均按大小显示出来。

import java.util.ArrayList; import java.util.Arrays; import java.util.Collections; import java.util.List; import java.util.Random; public class PokerGame { /**定义为静态以简化代码量*/ static List players; static ArrayList list = new ArrayList<>(); static String[] flowers = {"梅花","黑桃","方块","红桃"}; static String[] pointers = {"3","4","5","6","7","8","9","10","J","Q","K","A","2"}; int bossIndex; static{for(int i = 0; i < flowers.length; i++){for(int j = 0; j < pointers.length; j++){Poker p = new Poker(flowers[i],pointers[j],j); list.add(p); }}list.add(new Poker("小","王",13)); list.add(new Poker("大","王",14)); players = Arrays.asList(new Player(1,"胡灿"),new Player(2,"戴豪杰"),new Player(3,"马涛")); } /**随机地主*/ public void pushBoss(){/**随机一个索引，随到的为地主*/Random r = new Random(); bossIndex = r.nextInt(players.size()); players.get(bossIndex).setBoss(true); } /**洗牌功能*/ public void XiPai(){/**用Collections中的一个静态方法实现随机顺序集合*/Collections.shuffle(list); } /**发牌功能*/ public void FaPai(){/**每次按顺序给每人发一张牌直到51张牌发完*/for(int i = 0; i < 51; i+=3){players.get(0).getPokers().add(list.get(i)); players.get(1).getPokers().add(list.get(i+1)); players.get(2).getPokers().add(list.get(i+2)); }/**将剩余的三张牌发给地主*/for(int j = 51; j < 54; j++){players.get(bossIndex).getPokers().add(list.get(j)); } } /**排序功能*/ public void PaiXu(){/**用Collections的sort方法实现排序功能*/Collections.sort(players.get(0).getPokers()); Collections.sort(players.get(1).getPokers()); Collections.sort(players.get(2).getPokers()); } /**开始游戏*/ public void start(){pushBoss(); XiPai(); FaPai(); PaiXu(); for(Player p:players){System.out.println(p.getPokers()); } }}
