JAVA基础3季学完后手记（简易扑克牌游戏）

首先创建一个扑克牌类Card

package com.yx.card;

/**
 * 
 * @author
 * 卡牌类
 * point  点数
 * suit   花色
 * 
 */
public class Card {

    // 卡牌点数
    private String point;
    // 卡牌花色
    private String suit;

    public Card(String suit, String point){
        this.suit = suit;
        this.point = point;
    }

    public String getPoint() {
        return point;
    }

    public void setPoint(String point) {
        this.point = point;
    }

    public String getSuit() {
        return suit;
    }

    public void setSuit(String suit) {
        this.suit = suit;
    }

    @Override
    public String toString() {
        // TODO Auto-generated method stub
        return this.suit + " " + this.point;
    }

}

接着创建一个玩家类Player

package com.yx.person;

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

import com.yx.card.Card;

/**
 * 
 * @author 
 * 玩家类
 * id     ID
 * name   名字
 * cards  手上持有的牌
 *
 */
public class Player {
    // 玩家ID
    private int id;
    // 名字
    private  String name;
    // 手牌
    private ArrayList<Card> cards;
    // 玩家手中最大的手牌
    private Card maxCard;

    public Player(int id, String name){
        this.id = id;
        this.name = name;
        this.cards = new ArrayList<Card>();
    }

    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 ArrayList<Card> getCards() {
        return cards;
    }

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

    public Card getMaxCard() {
        return maxCard;
    }

    /**
     * 从玩家手中挑选出最大的那张手牌
     */
    public void setMaxCard( String[] points, String[] suits ) {
        Card tempMaxCard = this.cards.get(0);
        int tempMaxCardIdx =0;
        int tmpCardIdx=0;
        int tempMaxCardSuitIdx = 0;
        int tmpCardSuitIdx = 0;
        for(int i=1; i<this.cards.size(); i++){
            Card tmpCard = this.cards.get(i);
            for(int j=0; j<points.length; j++){
                if(tempMaxCard.getPoint().equals(points[j])){
                    tempMaxCardIdx = j;
                }
                if(tmpCard.getPoint().equals(points[j])){
                    tmpCardIdx = j;
                }
            }
//          System.out.println("比较点数时获取的索引值：" + tempMaxCardIdx + " : " + tmpCardIdx);
            if(tmpCardIdx > tempMaxCardIdx){
                tempMaxCard = tmpCard;
            }
            if(tmpCardIdx == tempMaxCardIdx){
                for(int k=0; k<suits.length; k++){
                    if(tempMaxCard.getSuit().equals(suits[k])){
                        tempMaxCardSuitIdx = k;
                    }
                    if(tmpCard.getSuit().equals(suits[k])){
                        tmpCardSuitIdx = k;
                    }
                }
//              System.out.println("比较 花色时获取的索引值：" + tempMaxCardSuitIdx + " : " + tmpCardSuitIdx);
                if(tmpCardSuitIdx < tempMaxCardSuitIdx){
                    tempMaxCard = tmpCard;
                }
            }
        }
        this.maxCard = tempMaxCard;
    }

    @Override
    public String toString() {
        // TODO Auto-generated method stub
        return this.name;
    }

}

然后我们在创建一个游戏类Game

package com.yx.game;
import java.util.ArrayList;
import java.util.InputMismatchException;
import java.util.List;
import java.util.Random;
import java.util.Scanner;

import com.yx.card.Card;
import com.yx.person.Player;

/**

 * 1、创建一副扑克：
 *    花色：黑桃、红桃、梅花、方块
 *    点数：2-10、J、Q、K、A  （不考虑大小王）
 * 2、创建两名或多名玩家：
 *       玩家至少有属性：ID， 名字，手牌等（手牌为扑克牌集合）
 * 3、洗牌：
 *    将创建好的扑克牌打乱顺序
 * 4、 将洗好的牌一张一张发给玩家，按一人一张轮流发
 * 5、 游戏：

 */
public class Game {

}

最后我们再建一个测试类，运行我们游戏

import com.yx.game.Game;

public class Application {

    public static void main(String[] args) {
        Game game = new Game();
        game.createPlayer();
        game.dealCard();
        game.playGame();
    }

}
