用java语言模拟斗地主的洗牌和发牌

斗地主的步骤

1.准备一个Map

2.准备一副牌<54个编号>

3.洗牌shuffle

4.依次给三个集合发牌,留三张给底牌

5.对每个集合进行排序

6.以键找值,通过map集合

//记得导包
public static void main(String[] args) {
//        1.准备一个Map
        HashMap map = new LinkedHashMap();
        //数据
        String[] colors = {"♥","♠","♣","♦"};
        String[] nums = {"3","4","5","6","7","8","9","10","J","Q","K","A","2"};
        int index = 1;
        //先遍历数字
        for (String num : nums) {
            //再遍历花色
            for (String color : colors) {
                //组合牌
                String card = color+num;
                //添加到map中
                map.put(index,card);
                index++;
            }
        }
       //单独添加大小王
        map.put(index,"小S");    
        index++;
        map.put(index,"大S");
//        2.准备一副牌(54个编号)
        ArrayList cards = new ArrayList();
        for (int i = 1; i < 55; i++) {
            cards.add(i);
        }
//        3.洗牌shuffle
        Collections.shuffle(cards);
//        4.依次给三个集合发牌,留三张给底牌
        ArrayList p1 = new ArrayList();
        ArrayList p2 = new ArrayList();
        ArrayList p3 = new ArrayList();
        ArrayList dp = new ArrayList();
        //轮流发牌
        for (int i = 0; i < cards.size() - 3; i++) {
            //取出牌
            Integer card = cards.get(i);
            //这个card应该给谁??
            if (i % 3 == 0) {
                p1.add(card);
            } else if (i % 3 == 1) {
                p2.add(card);
            } else {
                p3.add(card);
            }
        }
        //单独给底牌留三张
        Integer last1 = cards.get(cards.size() - 1);
        Integer last2 = cards.get(cards.size() - 2);
        Integer last3 = cards.get(cards.size() - 3);
        dp.add(last1);
        dp.add(last2);
        dp.add(last3);
//        5.对每个集合进行排序
        Collections.sort(p1);
        Collections.sort(p2);
        Collections.sort(p3);
        Collections.sort(dp);
//        6.以键找值,通过map集合
        //        7.看牌
        lookCards(p1,map);
        lookCards(p2,map);
        lookCards(p3,map);
        lookCards(dp,map);


    }

    private static void lookCards(ArrayList cards, HashMap map) {
        //遍历编号
        for (Integer cardId : cards) {
            //以键找值
            String card = map.get(cardId);
            System.out.print(card+" ");
        }
        System.out.println();
    }
