Java实现简易扑克牌游戏

功能描述

1、创建扑克牌。包括四种花色（黑桃，红心，梅花，方块），十三种点数（2-10，J，Q，K），不考虑大小王。

2、创建两个玩家。包括玩家id、姓名、手牌等集合，手牌为扑克牌的集合。

3、洗牌。将创建好的扑克牌打乱。

4、发牌。将洗牌之后的扑克牌集合，从第一张开始，发给两个玩家，安装一人 一张的方式，每人发两张。

5、游戏。比较两名玩家手中的扑克牌。规则为：去两名玩家手上点数最大的牌进行比较，点数大的赢，若点数一样大，就按照色花进行比较。

难点分析：

1、洗牌，如何将扑克牌进行打乱。（主要知识点Random，list.contains()）

2、扑克牌如何进行大小比较。（主要知识点collections.sort() , comparable）

实现代码

Card.java(扑克牌类)

package com.betty.dome2;

public class Card implements Comparable<Card>{
	// 牌面
	private String num;
	// 花色
	private String name;
	
	public Card(){		
	}
	
	public Card(String num,String name){
		this.num = num;
		this.name = name;
	}
	
	public String getNum() {
		return num;
	}
	public void setNum(String num) {
		this.num = num;
	}
	public String getName() {
		return name;
	}
	public void setName(String name) {
		this.name = name;
	}

	@Override
	public int hashCode() {
		final int prime = 31;
		int result = 1;
		result = prime * result + ((name == null) ? 0 : name.hashCode());
		result = prime * result + ((num == null) ? 0 : num.hashCode());
		return result;
	}

	@Override
	public boolean equals(Object obj) {
		if (this == obj)
			return true;
		if (obj == null)

		Card other = (Card) obj;
		if (name == null) {

		} else if (!name.equals(other.name))
			return false;
		if (num == null) {
			if (other.num != null)
				return false;
		} else if (!num.equals(other.num))
			return false;
		return true;
	}
	
	//  获取牌面大小
	private Integer getNumValue(String num){
		switch(num){
			case "A": return 12;
			case "2": return 13;
			case "3": return 1;
			case "4": return 2;

			case "10": return 8;
			case "J": return 9;
			case "Q": return 10;
			case "K": return 11;
		}
		return -1;
	}
	
	//  获取花色大小
	private Integer getNameValue(String name){
		switch(name){
			case "黑桃": return 4;
			case "红心": return 3;
			case "梅花": return 2;
			case "方块": return 1;
		}
		return -1;
	}
	
	@Override
	public int compareTo(Card card) {
		// 如果牌面相同就看花色
		int numCompare = getNumValue(this.num).compareTo(getNumValue(card.num));
		if(numCompare == 0){
			return getNameValue(this.name).compareTo(getNameValue(card.name));
		}
		return numCompare;
	}
}

Player.java（角色类）

package com.betty.dome2;

	//  角色姓名
	private String name;
	//  角色获得的牌
	List<Card> cardList;
	
	public Player(){
	}

	}

	public Integer getID() {

	}
