本文实例为大家分享了Java模拟实现斗地主发牌的具体代码,供大家参考,具体内容如下

题目:

模拟斗地主的发牌实现,54张牌,每张牌不同的花色(红心,黑桃,方块,梅花),牌的点数(3,4,5,6,7,8,9,10,J,Q,K,A,2,King,Queen),另有三名玩家,要求(使用面向对象的方式实现):

1、随机产生一名地主2、随机向三名玩家发牌,最后的底牌自动发给地主3、显示出每名玩家手中的牌4、要求根据点数自动对玩家手中的牌排序实现(*)

提示:玩家类,牌类,游戏类(算法)

步骤分析:

1.牌类:有点数和花色的差别,其中大王和小王只有点数没有花色

2.玩家类:玩家姓名,是否是地主,手中的牌(牌类集合)

3.游戏类(实现):(首先知道发牌规则,总共54张扑克牌,每人17张,剩下3张扑克给到地主手中。)

设置一个初始化块默认一副扑克牌,初始化三名玩家,随机一名玩家为地主,三名玩家随机获得17张牌,已获得的牌要从集合中删除。

代码实现:

牌类(Poker):

public class Poker { /**点数*/ private String point; /**花色*/ private String flower; public Poker() { } public Poker(String point, String flower) {this.point = point;this.flower = flower; } public String getPoint() {return point; } public void setPoint(String point) {this.point = point; } public String getFlower() {return flower; } public void setFlower(String flower) {this.flower = flower; } @Override public String toString() {if (Objects.isNull(flower)){return point;}return flower+''+point; }}

玩家类(Player):

public class Player { /**玩家昵称*/ private String nickname; private boolean boss; /**手中的牌*/ private List<Poker>pokers = new ArrayList<>(); public Player() { } public Player(String nickname) {this.nickname = nickname; } public String getNickname() {return nickname; } public void setNickname(String nickname) {this.nickname = nickname; } public boolean isBoss() {return boss; } public void setBoss(boolean boss) {this.boss = boss; } public List<Poker> getPokers() {return pokers; } public void setPokers(List<Poker> pokers) {this.pokers = pokers; } @Override public String toString() {return nickname+(boss?'(地主)':'(农民)')+pokers; }}

游戏类(Game):

public class Game { /**存储所有牌的集合*/ private List<Poker> list = new ArrayList<>(); private String[] points = {'3','4','5','6','7','8','9','10','J','Q','K','A','2'}; private String[] flowers = {'❤','♣','♦','♠'}; private List<Player> players = new ArrayList<>(); private Scanner sc = new Scanner(System.in); private static Random randomUtils = new Random(); //一副牌(笛卡尔积) {for (int i = 0; i<points.length; i++){ for (int j = 0; j < flowers.length; j++) {//将带花色的扑克牌加入集合list.add(new Poker(points[i],flowers[j])); }}//加入大小王list.add(new Poker('Queen',null));list.add(new Poker('King',null)); } /** * 初始化三名玩家 */ public void playerJoin(){System.out.println('请输入玩家昵称1');String p1 = sc.nextLine();System.out.println('请输入玩家昵称2');String p2 = sc.nextLine();System.out.println('请输入玩家昵称3');String p3 = sc.nextLine();players.add(new Player(p1));players.add(new Player(p2));players.add(new Player(p3)); } private void startGame(){//玩家加入playerJoin();//随机一个地主索引//nextInt(int bound)//返回伪随机的,均匀分布 int值介于0(含)和指定值(不包括),从该随机数生成器的序列绘制。int index = randomUtils.nextInt(players.size());//设置指定位的玩家为地主Player boss = players.get(index);boss.setBoss(true);System.out.println(boss.getNickname()+'是地主!');//开始发牌for (int i = 0; i < players.size(); i++) { //获取当前遍历到的玩家对象 Player player = players.get(i); for (int j = 0; j < 17; j++) {//随机获取一张牌给当前玩家int n = randomUtils.nextInt(list.size());//将随机到的牌存储到玩家的牌集合中player.getPokers().add(list.get(n));//将已经被取走的牌从原集合中删除list.remove(n); }}//将剩余三张牌给地主boss.getPokers().addAll(list);showPoker(); } private void showPoker(){for (Player player : players) { System.out.println(player);} } public static void main(String[] args) {new Game().startGame(); }}排序:

以上实现了基础的发牌功能,但没有对牌进行排序。java集合框架出现的同时,由于实际开发的数据的排序要求,所以JDK引入用于排序的两个接口:

Comparable<T>:自然排序

Comparator<T>:排序比较器

使用Comparable<T>:自然排序进行排序:

排序需要从三开始到大小王结束,所以需要新增一个进行排序比较的元素。

牌类:

//实现Comparable接口,实现其comparaTo(T t)方法public class Poker implements Comparable<Poker>/**用于排序的属性*/ private int sort; public Poker(String point, String flower, int sort) {this.point = point;this.flower = flower;this.sort = sort; } public int getSort() {return sort; } public void setSort(int sort) {this.sort = sort; } //实现方法进行排序@Override public int compareTo(Poker p) {return this.sort-p.sort;}

游戏类:

//一副牌(笛卡尔积) { int sort = 0;for (int i = 0; i<points.length; i++){ for (int j = 0; j < flowers.length; j++) {Poker p = new Poker(points[i],flowers[j],sort);//将带花色的扑克牌加入集合list.add(p); } sort++;}//加入大小王 list.add(new Poker('Queen', null,13)); list.add(new Poker('King', null,14)); } private void showPoker(){//排序实现Collections.sort(players.get(0).getPokers());Collections.sort(players.get(1).getPokers());Collections.sort(players.get(2).getPokers());for (Player player : players) { System.out.println(player);}}

使用Comparator<T>:排序比较器进行排序:

牌类:

public class Poker { /**点数*/ private String point; /**花色*/ private String flower; /**用于排序的属性*/ private int size; public Poker() { } public Poker(String point, String flower) {this.point = point;this.flower = flower; } public Poker(String point, String flower, int size) {this.point = point;this.flower = flower;this.size = size; } public String getPoint() {return point; } public void setPoint(String point) {this.point = point; } public String getFlower() {return flower; } public void setFlower(String flower) {this.flower = flower; } public int getSize() {return size; } public void setSize(int size) {this.size = size; } @Override public String toString() {if (Objects.isNull(flower)){return point;}return flower+''+point; } }

游戏类:

//一副牌(笛卡尔积) { int size = 0;for (int i = 0; i<points.length; i++){ for (int j = 0; j < flowers.length; j++) {Poker p = new Poker(points[i],flowers[j],size);//将带花色的扑克牌加入集合list.add(p); } //加入点数 size++;}//加入大小王 list.add(new Poker('Queen', null,13));list.add(new Poker('King', null,14)); } private void showPoker(){//排序实现for (int i = 0; i < players.size(); i++) { players.get(i).getPokers().sort(new Comparator<Poker>() {@Overridepublic int compare(Poker p1, Poker p2) { return p1.getSize()-p2.getSize();} }); System.out.println(players.get(i));} }

实现效果:

Java模拟实现斗地主发牌

扩展:

以上代码实现发牌原理是给每名玩家一次性随机17张牌,与现实发牌逻辑不符;按照现实发牌逻辑,需要先进行洗牌,打乱牌的顺序,然后轮流给每名玩家发牌,直到剩余三张牌发给地主。

实现原理:在jdk1.2集合框架出现的同时,新增用于对集合处理的工具类 java.util.Collections,这个类与java.util.Arrays同一时间出现;Collections中提供的所有方法都是静态的,方法包括,对集合:查找,排序,洗牌,转换,拷贝,查找最大值/最小值,集合反转,安全集合的获取等一系列静态方法。

这里用到洗牌方法,Collections.shuffle(List<?> list) (使用默认的随机源随机排列指定的列表)。

代码实现:(将游戏类中发牌的方法进行修改)

private void startGame() {//玩家加入playerJoin();//随机一个地主索引int index = randomUtils.nextInt(players.size());//设置指定位的玩家为地主Player boss = players.get(index);boss.setBoss(true);System.out.println(boss.getNickname() + '是地主!');//洗牌Collections.shuffle(list);//开始发牌//for (int i = 0; i < players.size(); i++) {// //获取当前遍历到的玩家对象// Player player = players.get(i);// for (int j = 0; j < 17; j++) {////随机获取一张牌给当前玩家//int n = randomUtils.nextInt(list.size());////将随机到的牌存储到玩家的牌集合中//player.getPokers().add(list.get(n));////将已经被取走的牌从原集合中删除//list.remove(n);// }//}for (int i = 0; i < list.size(); i++) { if (i < 51) {switch (i % 3) { case 0:players.get(0).getPokers().add(list.get(i));break; case 1:players.get(1).getPokers().add(list.get(i));break; case 2:players.get(2).getPokers().add(list.get(i));break; default:break;} } else {//将剩余三张牌给地主boss.getPokers().add(list.get(i)); }}showPoker(); }
