java模仿斗地主随机洗牌 发牌，TreeMap、ArrayList、TreeSet练习

/** * 模仿斗地主洗牌，随机发牌 * 使用TreeMap、ArrayList、TreeSet * 思想： * 使用TreeMap存54张牌，每张牌作为值，key为每张牌整数编号1-54，取出键进行乱序牌， * 之后发给三个人存在TreeSet自动会排序，然后偶循环通过键获得每张牌，斗地主不考虑花色 */import java.util.ArrayList;import java.util.Collections;import java.util.Set;import java.util.TreeMap;import java.util.TreeSet;public class Poker1 {public static void main(String[] args) {// 定义点数String[] point = { "3", "4", "5", "6", "7", "8", "9", "10", "J", "Q","K", "A", "2" };// 定义花色// String[] fC = { "红心", "方块", "黑桃", "梅花" };String[] fC = { "♥", "♦", "♠", "♣" };// 定义扑克集合TreeMap<Integer, String> mapPoker = new TreeMap<>();// 生成扑克int sum = 0;for (String s1 : point) {for (String s2 : fC) {mapPoker.put(++sum, s2.concat(s1));}}mapPoker.put(++sum, "小王");mapPoker.put(++sum, "大王");// System.out.println(mapPoker + "\n");//获取所有键Set<Integer> keys = mapPoker.keySet();//把键个封装到ArrayList集合，便于使用Collections集合工具类洗牌ArrayList<Integer> poker = new ArrayList<>();for (Integer integer : keys) {poker.add(integer);}// System.out.println("洗牌前key：" + poker);// 洗牌//使用集合工具类洗牌Collections.shuffle(poker);// System.out.println("洗牌后key：" + poker + "\n" + poker.size());// 派牌、码牌(TreeSet)，定义了三个人man1、man2、man3，底牌 diPokerTreeSet<Integer> man1 = new TreeSet<>();TreeSet<Integer> man2 = new TreeSet<>();TreeSet<Integer> man3 = new TreeSet<>();ArrayList<Integer> diPoker = new ArrayList<>(poker.subList(poker.size() - 3, poker.size()));//每人一张发牌for (int i = 0; i < poker.size() - 3; i++) {Integer s = poker.get(i);if (i % 3 == 1) {man1.add(s);} else if (i % 3 == 2) {man2.add(s);} else if (i % 3 == 0) {man3.add(s);}}// 看牌//三方牌装到ArrayList便于每个man遍历打印ArrayList<Set<Integer>> sets = new ArrayList<>();sets.add(man1);sets.add(man2);sets.add(man3);//外层遍历ArrayList的man封装，内层打印牌for (int i = 0; i < sets.size(); i++) {//三目嵌套打出每个人System.out.print(i == 0 ?
