需求如下
54张牌
每人得17张，留三张底牌
代码实现
Poker.java
public class Poker {public static void main(String[] args) {String[] colors = {"♠","♥","♣","♦"};String[] numbers = {"A","2","3","4","5","6","7","8","9","10","J","Q","K"};ArrayList<String> poker = new ArrayList<>();for (String number : numbers) {for (String color : colors) {poker.add(color+number);}}poker.add("🃏");poker.add("👲");Collections.shuffle(poker);//创建三个玩家ArrayList<String> player1 = new ArrayList<>();ArrayList<String> player2 = new ArrayList<>();ArrayList<String> player3 = new ArrayList<>();ArrayList<String> diPai = new ArrayList<>();for (int i = 0; i < poker.size(); i++) {if(i>=51){diPai.add(poker.get(i));}else if(i%3==0){player1.add(poker.get(i));}else if(i%3==1){player2.add(poker.get(i));}else if(i%3==2){player3.add(poker.get(i));}}TreeMap<String, String> player = new TreeMap();player.put("player1",player1.toString());player.put("player2",player2.toString());player.put("player3",player3.toString());System.out.println("底牌："+diPai);Random random = new Random();int index = random.nextInt(3);String playerName = (String) player.keySet().toArray()[index];player.put(playerName,player.get(playerName)+diPai.toString());for (Map.Entry<String, String> entry : player.entrySet()) {System.out.println(entry.getKey()+":"+entry.getValue());}}}
总结
需求具体化（做牌，打乱牌，发牌，亮底牌（随机抽选一个人获得底牌），全员展示牌）
