斗地主小游戏

一、准洗发

package Doudizhu;

import java.util.ArrayList;
import java.util.Collections;

public class PokerGame {
    //静态的集合才能给静态区使用
    static ArrayList<String> list = new ArrayList<>();

    //静态代码块
    //特点：随着类的加载而在加载的，而且只执行一次
    //如果多次玩游戏可以减少创建牌的次数
    static {
        //准备牌
        String[] huase = {"♣","♥","♦","♠"};
        String[] shuzi = {"2","3","4","5","6","7","8","9","10","J","Q","K",};
        //遍历数组进行拼接
        for (String s : shuzi) {
            for (String s1 : huase) {
                list.add(s1+""+s);
            }
        }
        //拼接上大小王
        list.add("大王");
        list.add("小王");
    }

    public PokerGame(){

        //洗牌
        Collections.shuffle(list);
        //发牌
        //创建字符串对象给用户添加牌
        ArrayList<String> lord = new ArrayList<>();
        ArrayList<String> player1 = new ArrayList<>();
        ArrayList<String> player2 = new ArrayList<>();
        ArrayList<String> player3 = new ArrayList<>();

        //遍历牌盒给每个用户发牌
        //使用普通的for循环，通过下标来发牌
        for (int i = 0; i < list.size(); i++) {
            if (i<3){
                lord.add(list.get(i));
            } else if (i%3==0) {
                player1.add(list.get(i));
            } else if (i%3==1) {
                player2.add(list.get(i));
            }else {
                player3.add(list.get(i));
            }
        }

        //看牌
        lookPoker("底牌",lord);
        lookPoker("小王",player1);
        lookPoker("小李",player2);
        lookPoker("小张",player3);
    }
    //使用函数打印每个玩家的牌
    public void lookPoker(String name,ArrayList<String> list){
        System.out.print(name+":");
        for (String poker : list) {
            System.out.print(poker+" ");
        }
        //换行
        System.out.println();
    }
}

二、第一种排序方式

对应思想

• 如果原始数据的规律非常复杂，我们可以先手动排序让每一个数据跟唯一的序号产生对应关系。
• 序号就是数字，规律非常简单，后续的所有操作，我们以序号为准
• 当真正需要操作原始数据时候，再通过序号找到原始数据即可。

方式一：利用序号进行排序

package Doudizhu2;

import java.util.ArrayList;
import java.util.Collections;
import java.util.HashMap;
import java.util.TreeSet;

public class PokerGame {
    static HashMap<Integer, String> hm = new HashMap<>();
    static ArrayList<Integer> list = new ArrayList<>();

    static {
        int serialNumber = 1;
        //准备牌
        String[] huase = {"♣","♥","♦","♠"};
        String[] shuzi = {"1","2","3","4","5","6","7","8","9","10","J","Q","K",};
        //遍历数组进行拼接
        for (String s : shuzi) {

            for (String s1 : huase) {
                hm.put(serialNumber,s1+s);
                list.add(serialNumber);
                serialNumber++;
            }
        }
        //拼接上大小王
        hm.put(serialNumber,"小王");
        list.add(serialNumber);
        serialNumber++;
        hm.put(serialNumber,"大王");
        list.add(serialNumber);
        System.out.println(hm);
        System.out.println(list);
    }
 public PokerGame(){
        //洗牌
         Collections.shuffle(list);
         //发牌
         //创建字符串对象给用户添加牌
        //使用TreeSet是因为其可以排列，以致发牌时可以自动的排序
         TreeSet<Integer> lord = new TreeSet<>();
         TreeSet<Integer> player1 = new TreeSet<>();
         TreeSet<Integer> player2 = new TreeSet<>();
         TreeSet<Integer> player3 = new TreeSet<>();

     for (int i = 0; i < list.size(); i++) {
         if(i<=2){
             lord.add(list.get(i));
             continue;
         }
         if (i%3==0){
             player1.add(list.get(i));
         } else if (i%3==1) {
             player2.add(list.get(i));
         }else {
             player3.add(list.get(i));
         }
     }
    //打印发给每个用户的牌
     lookPoker("底牌",lord);
     lookPoker("小王",player1);
     lookPoker("小李",player2);
     lookPoker("小张",player3);

 }
 public static void lookPoker(String name,TreeSet<Integer> list){
     System.out.print(name+":");

     for (Integer integer : list) {
         String poker = hm.get(integer);
         System.out.print(poker+" ");
     }
     System.out.println();
 }
}

三、第二种排序方式

方式二：给每一张牌计算价值

package Doudizhu3;

import java.util.ArrayList;
import java.util.Collections;
import java.util.Comparator;
import java.util.HashMap;

public class PokerGame {
    //静态的集合才能给静态区使用
    static ArrayList<String> list = new ArrayList<>();

    HashMap<String,Integer> hm = new HashMap<>();

    //静态代码块
    //特点：随着类的加载而在加载的，而且只执行一次
    //如果多次玩游戏可以减少创建牌的次数
    static {
        //准备牌
        String[] huase = {"♣","♥","♦","♠"};
        String[] shuzi = {"1","2","3","4","5","6","7","8","9","10","J","Q","K"};
        //遍历数组进行拼接
        for (String s : shuzi) {
            for (String s1 : huase) {
                list.add(s1+""+s);
            }
        }
        //拼接上大小王
        list.add(" 大王");
        list.add(" 小王");
    }

    public PokerGame(){

        //洗牌
        Collections.shuffle(list);
        //发牌
        //创建字符串对象给用户添加牌
        ArrayList<String> lord = new ArrayList<>();
        ArrayList<String> player1 = new ArrayList<>();
        ArrayList<String> player2 = new ArrayList<>();
        ArrayList<String> player3 = new ArrayList<>();

        //给每张牌加权重
        //如果这个牌在3~10的范围内，则去权重是其本身
        hm.put("J",11);
        hm.put("Q",12);
        hm.put("K",13);
        hm.put("1",14);
        hm.put("2",15);
        hm.put("小王",20);
        hm.put("大王",50);

        //遍历牌盒给每个用户发牌
        //使用普通的for循环，通过下标来发牌
        for (int i = 0; i < list.size(); i++) {
            if (i<3){
                lord.add(list.get(i));
            } else if (i%3==0) {
                player1.add(list.get(i));
            } else if (i%3==1) {
                player2.add(list.get(i));
            }else {
                player3.add(list.get(i));
            }
        }

        //计算牌的权重并且进行比较
        order(lord);
        order(player1);
        order(player2);
        order(player3);


        //看牌
        lookPoker("底牌",lord);
        lookPoker("小王",player1);
        lookPoker("小李",player2);
        lookPoker("小张",player3);
    }
    //使用函数打印每个玩家的牌
    public void lookPoker(String name,ArrayList<String> list){
        System.out.print(name+":");
        for (String poker : list) {
            System.out.print(poker+" ");
        }
        //换行
        System.out.println();
    }
    public void order(ArrayList<String> list){
        Collections.sort(list, new Comparator<String>() {
            @Override
            public int compare(String o1, String o2) {

                String color1 = o1.substring(0,1);
                int value1 = getValue(o1);

                String color2 = o2.substring(0,1);
                int value2 = getValue(o2);

                int i = value1 - value2;
                return i==0?color1.compareTo(color2):i;
            }
        });
    }
    public int getValue(String poker){
        String number = poker.substring(1);
        //拿着数字到map集合中看是否存在
        //存在，获取价值
        //不存在，类型转换
        if(hm.containsKey(number)){
            //存在，获取价值
            return hm.get(number);
        }else {
            //不存在，类型转换
            return Integer.parseInt(number);
        }
    }
}

五、游戏界面

六、面向对象设计（poker）

package Famerandlord.domain;

import javax.swing.*;
import java.awt.*;
import java.awt.event.MouseEvent;
import java.awt.event.MouseListener;
import java.awt.print.Book;

public class Poker extends JLabel implements MouseListener {
    //属性
    //牌的名字 数字+数字
    private String name;
    //牌是正反面
    private boolean up;

    //是否可以被点击
    private boolean canClick = false;
    //当前状态，表示当前已经被点击了
    //如果是没有被点击的状态，此时被点击了，会执行弹起的操作
    //如果是已经被点击的状态，此时被点击了，会执行降落的操作
    private boolean clicked = false;

    public Poker(String name,boolean up){
        this.name = name;
        this.up = up;

        //判断当前的牌是显示正面还是反面
        if(this.up){
            //显示正面
            turnPront();
        }else {
            //显示反面
            turnRear();
        }
        //设置牌的宽高
        this.setSize(71,96);
        //把牌显示出来
        this.setVisible(true);
        //给每一张牌添加监听
        this.addMouseListener(this);
    }

    public void turnPront(){
        //给牌设置正面
        //this.setIcon();(图片相对位置)
        this.up = true;
    }
    public void turnRear(){
        //this.setIcon();(图片相对位置)
        this.up = false;
    }


    @Override
    public void mouseClicked(MouseEvent e) {
        //点击
        //判断当前的牌是否可被点击
        if(canClick){
            //牌被点击之后要么升起要么降落
            //表示牌的位移像素
            int step = 0;
            if (clicked){
                //表示当前的牌已经被点击
                //降落（y增加 20像素）
                step = 20;
            }else {
                //表示当前的牌没有被点击
                //升起（y减少 20像素）
                step = -20;
            }
            //需要修改一下clicked变量记录的值
            clicked = !clicked;
            //修改一下牌的位置
            Point from = this.getLocation();
            //创建一个point的对象，表示结束位置
            Point to = new  Point(from.x,from.y+step);
            this.setLocation(to);

        }
    }

    @Override
    public void mousePressed(MouseEvent e) {
    }
    @Override
    public void mouseReleased(MouseEvent e) {
    }
    @Override
    public void mouseEntered(MouseEvent e) {
    }
    @Override

    }
}
