ArrayList实现

code

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

public class PokerDemo {
    public static void main(String[] args) {
        // 使用ArrayList添加一副牌
        ArrayList<String> arrayList = new ArrayList<String>();

        String[] colors = {"?", "?", "?", "?"};
        String[] numbers = {"A", "2", "3", "4", "5", "6", "7", "8", "9", "10", "J", "Q", "K"};

        for (String color : colors) {
            for (String number : numbers) {
                arrayList.add(color + number);
            }
        }

        arrayList.add("小王");
        arrayList.add("大王");

        // 洗牌
        Collections.shuffle(arrayList);

        // 发牌
        // 创建三个角色+底牌的集合
        ArrayList<String> user1 = new ArrayList<String>();
        ArrayList<String> user2 = new ArrayList<String>();
        ArrayList<String> user3 = new ArrayList<String>();
        ArrayList<String> dipaiArray = new ArrayList<String>();

        for (int i = 0; i < arrayList.size(); i++) {
            String poker = arrayList.get(i);
            if (i >= (arrayList.size() - 3)) {
                dipaiArray.add(poker);
            } else if (i % 3 == 0) {
                user1.add(poker);
            } else if (i % 3 == 1) {
                user2.add(poker);
            } else if (i % 3 == 2) {
                user3.add(poker);
            }
        }

        // 看牌
        show(user1, "user1");
        show(user2, "user2");
        show(user3, "user3");
        show(dipaiArray, "底牌");
    }

    // 看牌方法，传入ArrayList和用户名
    public static void show(ArrayList<String> arrayList, String name) {
        System.out.print(name + "的手牌是：");
        for (String poker : arrayList) {
            System.out.print(poker + " ");
        }
        System.out.println();
    }
}

HashMap实现

可以将手牌按照顺序显示

code

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

public class Poker {
    public static void main(String[] args) {
        // HashMap存储索引（key）和牌（vaule）
        HashMap<Integer, String> hashMap = new HashMap<Integer, String>();

        // ArrayList存储索引
        ArrayList<Integer> arrayList = new ArrayList<Integer>();

        String[] colors = {"?", "?", "?", "?"};
        String[] numbers = {"A", "2", "3", "4", "5", "6", "7", "8", "9", "10", "J", "Q", "K"};

        int index = 0;

        for (String number : numbers) {
            for (String color : colors) {
                hashMap.put(index, color + number);
                arrayList.add(index);
                index++;
            }
        }

        hashMap.put(index, "小王");
        arrayList.add(index);
        index++;
        hashMap.put(index, "大王");
        arrayList.add(index);

        // 洗索引
        Collections.shuffle(arrayList);

        // 测试输出
//        System.out.println(hashMap);
//        System.out.println(arrayList);

        // 三个玩家一个底牌，添加索引
        TreeSet<Integer> user1 = new TreeSet<Integer>();
        TreeSet<Integer> user2 = new TreeSet<Integer>();
        TreeSet<Integer> user3 = new TreeSet<Integer>();
        TreeSet<Integer> dipaiTree = new TreeSet<Integer>();

        for (int i = 0; i < arrayList.size(); i++) {
            int x = arrayList.get(i);
            if (i >= (arrayList.size() - 3)) {
                dipaiTree.add(x);
            } else if (i % 3 == 0) {
                user1.add(x);
            } else if (i % 3 == 1) {
                user2.add(x);
            } else if (i % 3 == 2) {
                user3.add(x);
            }
        }

        show("user1", user1 ,hashMap);
        show("user2", user2 ,hashMap);
        show("user3", user3 ,hashMap);
        show("底牌", dipaiTree ,hashMap);
    }

    // 根据索引遍历值
    public static void show(String name ,TreeSet<Integer> treeSet, HashMap<Integer, String> hashMap){
        System.out.print(name + "的手牌：");
        for(Integer key : treeSet){
            String s = hashMap.get(key);
            System.out.print(s + " ");
        }
        System.out.println();
    }
}
