简介

在很久很久以前,自己没事写的一个小练习。

封装了一个普扑克实体和一副牌,然后封装了一些方法,如:洗牌、抽牌等等。

使用的Java原生代码,没有任何第三方库,如果你想玩扑克,可以自行拷贝代码测试。

封装单张Poke的属性

java
/** * @class_name Poke * @effect 封装单张扑克牌 * @author Mr hu * @date 2018年11月10日 下午7:52:07 */ public class Poke { // 用于花色排序 private int color; private String colorname; // 用于点数排序 private int point; private String pointname; public int getColor() { return color; } public void setColor(int color) { this.color = color; } public String getColorname() { return colorname; } public void setColorname(String colorname) { this.colorname = colorname; } public int getPoint() { return point; } public void setPoint(int point) { this.point = point; } public String getPointname() { return pointname; } public void setPointname(String pointname) { this.pointname = pointname; } // 编写带参构造方法 public Poke(int color, String colorname, int point, String pointname) { this.color = color; this.colorname = colorname; this.point = point; this.pointname = pointname; } @Override public String toString() { return "["+colorname+":"+pointname+"]"; } }

封装一副扑克的行为

java
import java.util.ArrayList; import java.util.Collections; import java.util.Comparator; import java.util.List; /** * @class_name PokeBehavior * @effect 封装一副扑克牌的行为 * @author Mr hu * @date 2018年11月10日 下午10:29:16 */ public class PokeBehavior { /* * 编写生成一副扑克的方法 */ public static List<Poke> generatePoke() { // 创建Poke的List集合,用于存放一副扑克 List<Poke> pokelist = new ArrayList<Poke>(); // 创建四种花色从A—K各13张,共52张扑克,并添加到Poke集合中 for (int i = 1; i <= 4; i++) { for (int j = 1; j <= 13; j++) { String colorname = null; String pointname = null; // 1 ♡ | 2 ♢ | 3 ♤ | 4 ♣ switch (i) { case 1: colorname = "♥";break; case 2: colorname = "♢";break; case 3: colorname = "♤";break; case 4: colorname = "♣";break; } // 1 A | …… | 11 J | 12 Q | 13 K switch (j) { case 1: pointname = "A"; break; case 2: pointname = "2"; break; case 3: pointname = "3"; break; case 4: pointname = "4"; break; case 5: pointname = "5"; break; case 6: pointname = "6"; break; case 7: pointname = "7"; break; case 8: pointname = "8"; break; case 9: pointname = "9"; break; case 10: pointname = "10"; break; case 11: pointname = "J"; break; case 12: pointname = "Q"; break; case 13: pointname = "K"; break; } Poke poke = new Poke(i, colorname, j, pointname); pokelist.add(poke); } } // 创建大小王扑克并添加到Poke集合中 Poke pokemin = new Poke(5, "小", 14, "小王"); Poke pokemax = new Poke(6, "大", 15, "大王"); pokelist.add(pokemin); pokelist.add(pokemax); return pokelist; } /* * 编写打乱list集合(洗牌)的方法 */ public static List<Poke> disruptPoke(List<Poke> pokelist) { Collections.shuffle(pokelist); return pokelist; } /* * 编写按点数大小排序的方法 */ public static List<Poke> sortSize(List<Poke> pokelist) { //按照Poke的点数进行升序排列 Collections.sort(pokelist, new Comparator<Poke>() { public int compare(Poke p1, Poke p2) { if(p1.getPoint() > p2.getPoint()){ return 1; } if(p1.getPoint() == p2.getPoint()){ return 0; } return -1; } }); return pokelist; } /* * 编写按花色排序的方法 */ public static List<Poke> sortColor(List<Poke> pokelist) { //按照Poke的花色进行升序排列(1 ♡ | 2 ♢ | 3 ♤ | 4 ♣ ) Collections.sort(pokelist, new Comparator<Poke>() { public int compare(Poke p1, Poke p2) { if(p1.getColor() > p2.getColor()){ return 1; } if(p1.getColor() == p2.getColor()){ return 0; } return -1; } }); return pokelist; } /* * 编写既按照花色又按照大小排序(A2345……A2345……)的方法 * 分析后可知,先大小再花色即可 * 若先花色,再大小,就会变成(AAAA 2222 3333 ……)的形式 */ public static List<Poke> sortColorAndSize(List<Poke> pokelist) { //按照Poke的花色进行升序排列 Collections.sort(pokelist, new Comparator<Poke>() { public int compare(Poke p1, Poke p2) { if(p1.getColor() > p2.getColor()){ return 1; } if(p1.getColor() == p2.getColor()){ return 0; } return -1; } }); // 调用编写好的花色排序方法 PokeBehavior.sortColor(pokelist); return pokelist; } /* * 编写抽取随机抽取一张扑克的方法 */ public static Poke getOnePoke(List<Poke> pokelist) { Poke poke=pokelist.get((int) (Math.random()*53)); return poke; } }

测试

java
import java.util.List; /** * @class_name PokeMain * @effect 测试 * @author Mr hu * @date 2018年11月10日 下午10:28:45 */ public class PokeMain { // 生成一副扑克 public static List<Poke> pokelist = PokeBehavior.generatePoke(); public static void main(String[] args) { // 输出初始状态poke System.out.println("原生poke:"); for (Poke poke : pokelist) { System.out.print(poke.toString()); int index = pokelist.indexOf(poke); if (index == 12 || index == 25 || index == 38 || index == 51) { System.out.println(); } } System.out.println(); // 测试打乱顺序 pokelist = PokeBehavior.disruptPoke(pokelist); System.out.println("打乱顺序poke:"); for (Poke poke : pokelist) { System.out.print(poke.toString()); int index = pokelist.indexOf(poke); if (index == 12 || index == 25 || index == 38 || index == 51) { System.out.println(); } } System.out.println(); // 测试按花色排序 pokelist = PokeBehavior.sortColor(pokelist); System.out.println("按花色排序poke:"); for (Poke poke : pokelist) { System.out.print(poke.toString()); int index = pokelist.indexOf(poke); if (index == 12 || index == 25 || index == 38 || index == 51) { System.out.println(); } } System.out.println(); // 测试按大小排序(先打乱上一步的花色排序) pokelist = PokeBehavior.disruptPoke(pokelist); pokelist = PokeBehavior.sortSize(pokelist); System.out.println("按大小排序poke:"); for (Poke poke : pokelist) { System.out.print(poke.toString()); int index = pokelist.indexOf(poke); if (index == 3 || index == 7 || index == 11 || index == 15 || index == 19 || index == 23 || index == 27|| index == 31 || index == 35 || index == 39 || index == 43 || index == 47 || index == 51) { System.out.println(); } } System.out.println(); // 测试既按大小又按花色排序 pokelist = PokeBehavior.sortColorAndSize(pokelist); System.out.println("既按大小又按花色排序poke:"); for (Poke poke : pokelist) { System.out.print(poke.toString()); int index = pokelist.indexOf(poke); if (index == 12 || index == 25 || index == 38 || index == 51) { System.out.println(); } } System.out.println(); System.out.println("随机抽取一个poke:"); System.out.println(PokeBehavior.getOnePoke(pokelist).toString()); } }
