Java入门第三季第7章--简易扑克牌游戏-原创手记-慕课网

一、分析：
1.扑克牌，属性：花色、点数；实现接口Comparable的CompareTo方法，通过点数和花色List的下标来比较大小。
2.扑克牌列表：属性：扑克牌类的List；在构造函数中，使用LinkedList给属性实例化。方法：扑克牌打乱顺序使用Collections的shuffle方法。
3.玩家：属性：ID,姓名，手牌，手牌为扑克牌的集合。
4.扑克牌游戏，按照实际游戏的顺序写出。
二、代码

扑克牌

package com.imooc.java3.ch7x;

import java.util.Arrays;
import java.util.LinkedList;

public class Poker implements Comparable<Poker>{
    private String kind;
    private String point;
    public Poker() {
        super();
    }
    public Poker(String kind, String point) {
        super();
        this.kind = kind;
        this.point = point;
    }
    public String getKind() {
        return kind;
    }
    public void setKind(String kind) {
        this.kind = kind;
    }
    public String getPoint() {
        return point;
    }
    public void setPoint(String point) {
        this.point = point;
    }
    @Override
    public String toString() {
        return kind + point;
    }

    @Override
    public int compareTo(Poker o) {
        //扑克牌分为四种花色：黑桃、方块、梅花和红桃。
        LinkedList<String> kinds = new LinkedList<String>();
        kinds.addAll(Arrays.asList(new String[]{"黑桃","方块","梅花","红桃"}));

        //扑克牌中每一组花色有十三张牌。
        LinkedList<String> numbers = new LinkedList<String>();
        String[] numlist = "2,3,4,5,6,7,8,9,10,J,Q,K,A".split(",");
        numbers.addAll(Arrays.asList(numlist));

        if(!this.getPoint().equals(o.getPoint())){
            return numbers.indexOf(this.getPoint())-numbers.indexOf(o.getPoint());
        }else if(!this.getKind().equals(o.getKind())){
            return kinds.indexOf(this.getKind())-kinds.indexOf(o.getKind());
        }
        return 0;
    }
}

2.扑克牌列表

package com.imooc.java3.ch7x;

import java.util.Arrays;
import java.util.Collections;
import java.util.LinkedList;
import java.util.List;

import org.junit.Test;

public class PokerCards {
    private List<Poker> cards;

    public PokerCards() {
        super();
        this.cards = new LinkedList<Poker>();
    }

    public List<Poker> getCards() {
        return cards;
    }

    @Test
    public void initial(){
        //扑克牌分为四种花色：黑桃、方块、梅花和红桃。
        LinkedList<String> kinds = new LinkedList<String>();
        kinds.addAll(Arrays.asList(new String[]{"黑桃","方块","梅花","红桃"}));

        //扑克牌中每一组花色有十三张牌。
        LinkedList<String> numbers = new LinkedList<String>();
        String[] numlist = "2,3,4,5,6,7,8,9,10,J,Q,K,A".split(",");
        numbers.addAll(Arrays.asList(numlist));

        for(String kind:kinds){
            for(String num:numbers){
                this.cards.add(new Poker(kind,num));
            }
        }
    }

    public void showForeach(){
        for(Poker pk:this.cards){
            System.out.println(pk);
        }
    }
    /**
     * 洗牌
     */
    @Test
    public void  shuffleCards(){
        Collections.shuffle(this.cards);
    }

}

3.玩家

package com.imooc.java3.ch7x;

import java.util.HashSet;
import java.util.Set;

public class Player {
    private String id;
    private String name;
    private Set<Poker> cardsSet;

    public Player() {
        super();
        this.cardsSet = new HashSet<Poker>();
    }
    public Player(String id, String name) {
        super();
        this.id = id;
        this.name = name;
        this.cardsSet = new HashSet<Poker>();
    }
    public String getId() {
        return id;
    }
    public void setId(String id) {
        this.id = id;
    }
    public String getName() {
        return name;
    }
    public void setName(String name) {
        this.name = name;
    }
    public Set<Poker> getCardsSet() {
        return cardsSet;
    }
    public void setCardsSet(Set<Poker> cardsSet) {
        this.cardsSet = cardsSet;
    }

    public void addCard(Poker poker){
        this.cardsSet.add(poker);
    }

    public void clearCards(){
        this.cardsSet.clear();
    }
    @Override
    public String toString() {
        return "Player [id=" + id + ", name=" + name + ", cardsSet=" + cardsSet + "]";
    }

}

package com.imooc.java3.ch7x;

import java.util.ArrayList;
import java.util.Collections;
import java.util.List;
import java.util.Scanner;

public class PokerGame {
    public static void main(String[] args) {
        //创建一副扑克牌
        PokerCards pc = new PokerCards();
        System.out.println("--------创建扑克牌----------------");
        pc.initial();
        System.out.println("--------扑克牌创建成功！----------------");
        System.out.println(pc.getCards());

        //洗牌；
        System.out.println("--------开始洗牌----------------");
        pc.shuffleCards();
        System.out.println("--------洗牌结束！----------------");
        System.out.println(pc.getCards());

        //创建两个玩家；
        System.out.println("--------创建玩家----------------");
        List<Player> pylist = new ArrayList<Player>();
        Scanner sc = new Scanner(System.in);
        for(int i =0;i<2;i++){
            System.out.println("请输入第"+(i+1)+"位玩家的ID和姓名");
            Player py = new Player();
            System.out.println("输入ID:");
            py.setId(sc.next());
            System.out.println("输入姓名:");
            py.setName(sc.next());
            pylist.add(py);
            System.out.println("----欢迎玩家："+py.getName());
        }
        sc.close();

        int count =0;
        while(true){
            System.out.println("------------开始发牌！------------");
            //发牌：
            for(int i =(count*4);i<(count+1)*4;i+=2){
                System.out.println("玩家："+pylist.get(0).getName()+"-拿牌");
                pylist.get(0).addCard(pc.getCards().get(i));
                System.out.println("玩家："+pylist.get(1).getName()+"-拿牌");
                pylist.get(1).addCard(pc.getCards().get(i+1));
            }
            System.out.println("------------发牌结束！------------");

            System.out.println("------------开始游戏------------");
            //给玩家的牌排序
            Poker py1Card = Collections.max(pylist.get(0).getCardsSet());
            System.out.println("玩家："+pylist.get(0).getName()+"最大的手牌为："+py1Card);
            Poker py2Card = Collections.max(pylist.get(1).getCardsSet());
            System.out.println("玩家："+pylist.get(1).getName()+"最大的手牌为："+py2Card);

            int res = py1Card.compareTo(py2Card);
            if(res<0){
                System.out.println("------------玩家："+pylist.get(1).getName()+"赢！！！");
            }else if(res>0){
                System.out.println("------------玩家："+pylist.get(0).getName()+"赢！！！");
            }else{
                System.out.println("合局！！");
            }
            //显示玩家的牌；
            System.out.println("玩家各自的手牌为：");
            System.out.println(pylist.get(0).getName()+":"+pylist.get(0).getCardsSet());
            System.out.println(pylist.get(1).getName()+":"+pylist.get(1).getCardsSet());

            //清空玩家的数据；
            pylist.get(0).clearCards();
            pylist.get(1).clearCards();

            count++;
            if(count>=3||count*4>=52){
                break;
            }
        }
