java实现斗地主游戏

感想：

第一次写博客，感觉编辑器挺复杂厉害的，感觉自己的内容挺简单的。有什么问题请多多指教！

思路：

1、创建一个扑克牌的实体类Poker，设置了四个参数：花色、数字、牌值（判断大小）、是否地主牌，实现getset方法和构造方法；
2、创建一个玩家的实体类Player，设置了四个参数： 初始牌集合，排序后牌集合，牌值集合，是否地主，实现getset方法和构造方法；
3、洗牌：循环嵌套花色数组跟数字数组生成52个Poker，手动加入大小王Poker，放进map(int,Poker)里面，利用Collections.shuffle随机排序map的key，再根据key生成排序后的Poker集合
4、发牌：生成3个玩家对象，拿到洗牌后的集合，前51张牌为玩家牌，后3张为地主牌，在51张牌中随机一张为地主牌，遍历玩家牌分配个每一个Player，同时根据玩家牌的牌值生成集合grades存进Player对象中，将grades转为int数组并进行升序排序，根据grade取得新Poker集合分配给玩家。

Poker类：

package com.company;

public class Poker {
  private String color;
  private String number;
  private int grade;
  boolean isLandowners;

 public boolean isLandowners() {
  return isLandowners;
 }

 public void setLandowners(boolean landowners) {
  isLandowners = landowners;
 }

 public int getGrade() {
  return grade;
 }

 public void setGrade(int grade) {
  this.grade = grade;
 }

 public String getColor() {
  return color;
 }

 public void setColor(String color) {
  this.color = color;
 }

 public String getNumber() {
  return number;
 }

 public void setNumber(String number) {
  this.number = number;
 }

 public Poker() {
 }

 public Poker(String color, String number ,int grade,boolean isLandowners) {
  this.color = color;
  this.number = number;
  this.grade=grade;
  this.isLandowners=isLandowners;
 }

 public String toString() {
  return this.getColor()+this.getNumber();
 }
}

Player类：

package com.company;

import java.util.ArrayList;
import java.util.LinkedList;

public class Player {
 private ArrayList<Poker> pokers;
 private boolean isLandower;
 private ArrayList<Poker> newPokers;
 private LinkedList<Integer> grades;

 public LinkedList<Integer> getGrades() {
  return grades;
 }

 public void setGrades(LinkedList<Integer> grades) {
  this.grades = grades;
 }

 public ArrayList<Poker> getNewPokers() {
  return newPokers;
 }

 public void setNewPokers(ArrayList<Poker> newPokers) {
  this.newPokers = newPokers;
 }

 public boolean isLandower() {
  return isLandower;
 }

 public void setLandower(boolean landower) {
  isLandower = landower;
 }

 public Player() {
 }

 public ArrayList<Poker> getPokers() {
  return pokers;
 }

 public void setPokers(ArrayList<Poker> pokers) {
  this.pokers = pokers;
 }
}

洗牌：

/*洗牌*/
 public static LinkedList<Poker> getPokerList() {
  LinkedList<Poker> pokers = new LinkedList<Poker>();
  LinkedList<Poker> newPokers = new LinkedList<Poker>();
  ArrayList<Integer> arrayList = new ArrayList<>();
  int[] arr;

  /*生成54张扑克牌（Poker对象）*/
  /*用嵌套循环生成从方块3到黑桃2的Poker对象，放进Poker的LinkedList保证顺序*/
  String[] colors = {"♦", "♣", "♥", "♠"};
  String[] numbers = {"3", "4", "5", "6", "7", "8", "9", "10", "J", "Q", "K", "A", "2"};
  for (int i = 0; i < numbers.length; i++) {
   for (int j = 0; j < colors.length; j++) {
    Poker p = new Poker(colors[j], numbers[i], (4 * i) + j + 1, false);
    pokers.add(p);
   }
  }
  /*添加大小王*/
  pokers.add(new Poker("black", "☆", 53, false));
  pokers.add(new Poker("red", "☆", 54, false));

  /*将生成的54张扑克牌从1到54放进map*/
  for (int z = 1; z <= pokers.size(); z++) {
   map.put(z, pokers.get(z - 1));
  }
  /*遍历Map,将每个Poker对应的key放进 ArrayList<Integer> arrayList */
  Set<Map.Entry<Integer, Poker>> set = map.entrySet();
  Iterator it = set.iterator();
  while (it.hasNext()) {
   Map.Entry<Integer, Poker> e = (Map.Entry<Integer, Poker>) it.next();
   arrayList.add(e.getKey());
  }
  /*利用Collections.shuffle随机排序key*/
  Collections.shuffle(arrayList);
  /*将乱序后的key对于的Poker放进newPokers里面 */
  for (Integer i : arrayList) {
   newPokers.add(map.get(i));
  }

  return newPokers;
 }

发牌：

/*发牌*/
 /*根据玩家人数生成Player，默认num=3*/
 private static void sentPoker(int num) {
  /*获取洗牌后的LinkedList,保证顺序*/
  LinkedList<Poker> Allpokers = getPokerList();
  ArrayList<Poker> pokers = new ArrayList<>();
  ArrayList<Poker> BottomPokers = new ArrayList<>();

  /*生成玩家对象*/
  for (int i = 0; i < num; i++) {
   Player p = new Player();
   players.add(p);
  }
  /*前50张牌为玩家牌，后三张为底牌*/
  for (int p = 0; p < Allpokers.size(); p++) {
   if (p <= 50) {
    pokers.add(Allpokers.get(p));
   } else {
    BottomPokers.add(Allpokers.get(p));
   }
  }
  /*玩家牌中随机一张为地主牌*/
  Random rand = new Random();
  int s = rand.nextInt(51);
  pokers.get(s).setLandowners(true);
  System.out.println("地主牌: " + pokers.get(s));

  /*根据num生成Player对象*/
  for (int j = 0; j < num; j++) {
   /*玩家的牌值集合*/
   LinkedList<Integer> grades = new LinkedList<>();
   /*玩家的手牌集合*/
   ArrayList<Poker> playerPokers = new ArrayList<Poker>();

   /*根据玩家个数分配玩家牌*/
   for (int z = j; z < pokers.size(); z = z + num) {
    playerPokers.add(pokers.get(z));
    grades.add(pokers.get(z).getGrade());
    players.get(j).setPokers(playerPokers);
    players.get(j).setGrades(grades);
   }
   /*根据玩家牌中的地主牌设置玩家是否地主*/
   for (Poker p : players.get(j).getPokers()) {
    if (p.isLandowners() == true) {
     players.get(j).setLandower(true);
    }
   }
   /*根据玩家的牌值集合生成数组*/
   Integer[] gs = new Integer[players.get(j).getGrades().size()];
   grades.toArray(gs);
   /*排序数组，由低到高*/
   Arrays.sort(gs);

   /*排序后的玩家牌*/
   ArrayList<Poker> newPokers = new ArrayList<>();
   for (int g = 0; g < gs.length; g++) {
    Poker p = map.get(gs[g]);
    newPokers.add(p);
   }
   players.get(j).setNewPokers(newPokers);
   System.out.println("玩家" + (j + 1) + ": " + players.get(j).getNewPokers() + " 是否地主：" + players.get(j).isLandower());
  }

  System.out.print("底牌为： ");
  for (Poker p : BottomPokers) {
   System.out.print(p + " ");
  }
 }

效果如下：
