模拟斗地主发牌功能的设计与实现

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)

牌类

牌有牌面值、花色及实际大小三个属性

import java.util.Objects;

public class Card {
	
	private String name;//牌面值
	private String flower;//花色
	private int num;//大小点数
	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 flower + name + "-" + num + "点";
		}
		return name + "-" + num + "点";
	}
}

玩家类

玩家有编号、姓名、是否是地主、手中牌集合四个属性

import java.util.ArrayList;

public class Player {
	
	private int id;
	private String name;
	private boolean boss;
	private ArrayList<Card> cards = new ArrayList<>();
	public Player() {
		super();
	}
	public Player(int id, String name, boolean boss, ArrayList<Card> cards) {
		super();
		this.id = id;
		this.name = name;
		this.boss = boss;
		this.cards = cards;
	}
	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<Card> getCards() {
		return cards;
	}
	public void setCards(ArrayList<Card> cards) {
		this.cards = cards;
	}
	@Override
	public String toString() {
		return name + (boss ? "(地主)" : "(农民)") + "--牌：" + cards;
	}
}

游戏类

实现一副扑克牌（54张），并实现随机一位地主和根据玩家角色分发牌的功能。
1、定义牌集合（动态数组）、牌面值集合（不含大小王）、牌花色集合、玩家集合（动态数组）、随机数生成器
2、用笛卡尔积组合牌面值和花色得到52张牌，添加进牌集合，再添加大小王
3、创建三名玩家对象并添加进玩家集合
4、在玩家集合中根据动态数组下标随机一位地主
5、遍历玩家集合得到三位玩家，每位玩家在牌集合里随机抽取17次，每抽取一张，牌数组删除一张，玩家牌集合添加一张，最后剩下三张加入地主的牌集合，完成发牌

import java.util.Random;
import java.util.Scanner;
