Java 纸牌游戏模拟器：规则、代码和玩法

使用 Java 语言编写一个模拟纸牌游戏软件

该软件具有以下功能：

1. 创建一副扑克牌（共 54 张） 包括四种花色：黑桃，红桃，梅花，方片，包括十三种点数：2-10，J,Q,K,A
2. 创建两名玩家（or 多名） 玩家至少要有 ID，姓名，手牌等属性，手牌为扑克牌的集合
3. 将创建好的扑克牌进行随机洗牌。
4. 从洗牌后的扑克牌的第一张开始，发给每个玩家，按照一人一张的方式，每人发三张牌
5. 比较两名玩家手中的扑克牌，比较规则为：取两人各自手中点数最大的牌进行比较，点数大的赢；若两人各自的点数最大的牌相等，则再按照花色比较，大小由黑(4)、红(3)、梅(2)、方(1)，花色大者获胜。
6. 输出比较结果，显示每位玩家的手牌和最终获胜者。
7. 提供重新开始游戏的选项。

代码实现如下：

    SPADE, HEART, CLUB, DIAMOND
