**需求：**写一个可以给斗地主玩家随机发牌的程序。a：牌可以随机发给三个玩家b：在控制台打印每个玩家的牌。c：对每个玩家手中的牌按照大小排序。

牌的花色："♠", "♥", "♣", "♦"

思路：创建一个容器存储所有的牌，再创建三个容器分别表示三个用户的牌，三个用户轮流从第一个容器中取牌，剩下三张为底牌。把大王和小王也算进去。可以封装一个类表示牌  
**代码：**Main.java

package hcq.hw;
    
    import java.util.List;
    import java.util.TreeSet;
    
    public class Main {
    
    	public static void main(String[] args) {
    		Poker poker = new Poker();
    		
    		poker.getPoker();// 得到牌
    		// 每个玩家存储牌的容器
    		TreeSet<Card> p1 = new TreeSet<>();
    		TreeSet<Card> p2 = new TreeSet<>();
    		TreeSet<Card> p3 = new TreeSet<>();
    		// 洗牌和发牌操作 返回的是底牌
    		List<Card> dealPoker = poker.dealPoker(p1, p2, p3);
    
    		// 删除牌
    		System.err.println("玩家一：" + p1);
    		System.err.println("玩家二：" + p2);
    		System.err.println("玩家三：" + p3);
    		System.out.println("底牌    ：" + dealPoker);
    	}
    
    }

Poker.java

package hcq.hw;
    
    import java.util.Collection;
    import java.util.Collections;
    import java.util.LinkedList;
    import java.util.List;
    
    public class Poker {
    
    	private LinkedList<Card> pokers = new LinkedList<>();
    	private char[] flowers = { '♦', '♣', '♥', '♠' };
    	private char[] numbers = { '3', '4', '5', '6', '7', '8', '9', '0', 'J', 'Q', 'K', 'A', '2' };
    
    	public Poker() {
    		for (int i = 0; i < numbers.length; i++) {
    			for (int j = 0; j < flowers.length; j++) {
    				pokers.add(new Card(numbers[i], flowers[j], j + i * flowers.length));
    			}
    		}
    
    		pokers.add(new Card('王', '小', 99));
    		pokers.add(new Card('王', '大', 100));
    
    	}
    
    	// 初始化牌
    	public static Poker getPoker() {
    		return new Poker();
    	}
    
    	// 打印牌
    	public void showPoker() {
    		for (Card c : pokers) {
    			System.out.println(c.toString());
    		}
    	}
    
    	// 洗牌和发牌方法
    	public List<Card> dealPoker(Collection<Card> play1, Collection<Card> play2, Collection<Card> play3) {
    		Collections.shuffle(pokers);// 洗牌
    		while (pokers.size() > 3) {
    			play1.add(pokers.removeFirst());
    			play2.add(pokers.removeFirst());
    			play3.add(pokers.removeFirst());
    		}
    		return pokers;// 返回3张底牌
    	}
    
    }

Card.java

package hcq.hw;
    
    public class Card implements Comparable<Card> {
    	private char number;// 号码
    	private char flower;// 花色
    	private int grade;// 等级
    
    	public Card(char number, char flower, int grade) {
    		super();
    		this.number = number;
    		this.flower = flower;
    		this.grade = grade;
    	}
    
    	@Override
    	public String toString() {
    		return "[" + flower + number + "]";
    	}
    
    	public char getNumber() {
    		return number;
    	}
    
    	public void setNumber(char number) {
    		this.number = number;
    	}
    
    	public char getFlower() {
    		return flower;
    	}
    
    	public void setFlower(char flower) {
    		this.flower = flower;
    	}
    
    	public int getGrade() {
    		return grade;
    	}
    
    	public void setGrade(int grade) {
    		this.grade = grade;
    	}
    
    	@Override
    	public int compareTo(Card o) {
    		return o.grade - this.grade;
    	}
    
    }
