参考斗地主的游戏规则，完成一个发牌的功能(54张牌，考虑点数，花色；三名玩家，其中地主比其他玩家多3张牌)

代码如下：

牌类

import java.util.Objects;

/**
 * 3-10 J Q K A 2 King Queen 牌类
 * 
 * @author Administrator
 *
 */
public class Card {

 /** 牌面值 */
 private String name;
 /** 花色 */
 private String flower;
 /** 大小点数 */
 private int num;

 public Card() {
 super();
 }

 public Card(String name, String flower, int num) {
 super();
 this.name = name;
 this.flower = flower;
 this.num = num;
 }

 public String getName() {
 return name;
 }

 public void setName(String name) {
 this.name = name;
 }

 public String getFlower() {
 return flower;
 }

 public void setFlower(String flower) {
 this.flower = flower;
 }

 public int getNum() {
 return num;
 }

 public void setNum(int num) {
 this.num = num;
 }

 @Override
 public String toString() {
 if(Objects.nonNull(flower)) {
  return name + "-" + flower;
 }
 return name;
 }

}

玩家类

public class Player {

 /**玩家ID*/
 private int id;
 /**玩家姓名*/
 private String name;
 /**是否是地主*/
 private boolean boss;
 /**牌集合*/
 private ArrayList cards = new ArrayList();

 public Player(int id, String name, boolean boss, ArrayList cards) {
 super();
 this.id = id;
 this.name = name;
 this.boss = boss;
 this.cards = cards;
 }

 public Player() {
 super();
 }

 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 boolean isBoss() {
 return boss;
 }

 public void setBoss(boolean boss) {
 this.boss = boss;
 }

 public ArrayList getCards() {
 return cards;
 }

 public void setCards(ArrayList cards) {
 this.cards = cards;
 }

 @Override
 public String toString() {
 return name +(boss? "(地主):":"(农名):")+ cards;
 }

}

管理类

public class GameManage {

 private static Random randomGen = new Random();
 /** 声明所有牌的集合 */
 private static ArrayList all = new ArrayList();
 /** 用于生成牌的牌面值 */
 private static String[] names = { "3", "4", "5", "6", "7", "8", "9", "10", "J", "Q", "K", "A", "2", "小王","大王" };
 /** 用于生成牌的花色 */
 private static String[] flowers = { "红桃", "方块", "梅花", "黑桃" };
 private ArrayList players = new ArrayList();

 static {
 int i = 0;
 for (; i < names.length - 2; i++) {
  for (int j = 0; j < flowers.length; j++) {
  Card c = new Card(names[i], flowers[j], i);
  all.add(c);
  }
 }
 // 将大小王加入
 all.add(new Card(names[names.length - 2], null, i++));
 all.add(new Card(names[names.length - 1], null, i++));

 }

 /**
 * 加入玩家
 */
 private void addPlayer() {
 Scanner sc = new Scanner(System.in);
 System.out.println("请输入玩家1名称:");
 String name1 = sc.nextLine();
 System.out.println("请输入玩家2名称:");
 String name2 = sc.nextLine();
 System.out.println("请输入玩家3名称:");
 String name3 = sc.nextLine();

 Player p1 = new Player();
 p1.setId(1);
 p1.setName(name1);

 Player p2 = new Player();
 p1.setId(2);
 p2.setName(name2);

 Player p3 = new Player();
 p1.setId(3);
 p3.setName(name3);

 // 将三名玩家加入集合
 players.add(p1);
 players.add(p2);
 players.add(p3);
 }

 /**
 * 随机地主
 */
 private void randomBoss() {
 // 添加玩家
 addPlayer();
 // 随机地主索引
 int i = randomGen.nextInt(players.size());
 // 设置指定位置的玩家为地主
 players.get(i).setBoss(true);
 }

 public ArrayList sendCard() {
 randomBoss();

 // 对每一名玩家遍历
 for (Player p : players) {
  // 先为每一位玩家随机发17张牌
  for (int i = 0; i < 17; i++) {
  // 随机一张牌的索引
  int cardIndex = randomGen.nextInt(all.size());
  // 获取随机索引位置的牌
  Card card = all.get(cardIndex);
  // 将随机的牌加入当前遍历玩家的集合
  p.getCards().add(card);
  // 从源集合中移除这张牌
  all.remove(card);
  }
 }
 // 最后三张牌给地主
 for (Player p : players) {
  if (p.isBoss()) {
  // 将all集合中的所有元素加入地主的集合
  p.getCards().addAll(all);
  }
 }
 
 return players;
 }
