Java实现简易扑克牌游戏的完整实例

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)
return false;
if (getClass() != obj.getClass())
return false;
Card other = (Card) obj;
if (name == null) {
if (other.name != null)
return false;
} 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 "5": return 3;
case "6": return 4;
case "7": return 5;
case "8": return 6;
case "9": return 7;
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;

import java.util.ArrayList;
import java.util.List;

public class Player {
//  角色id
private Integer ID;
//  角色姓名
private String name;
//  角色获得的牌

public Player(){
}

public Player(Integer ID,String name){
this.ID = ID;
this.name = name;
this.cardList = new ArrayList<Card>();
}

public Integer getID() {
return ID;
}

public void setID(Integer iD) {
ID = iD;
}

public String getName() {
return name;
}

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

}
