主要内容：这里使用collection集合，模拟香港电影中大佬们玩的扑克牌游戏。
1、游戏规则：两个玩家每人手中发两张牌，进行比较。比较每个玩家手中牌最大的点数，大小由A-2，点数大者获胜。如果点数相同，则比较花色，大小由黑(4)、红(3)、梅(2)、方(1)，花色大者获胜。
2、实现步骤：
- 创建一副扑克牌A-2，四种花色黑(4)、红(3)、梅(2)、方(1)共52张牌；
- 创建两个玩家包含玩家ID和姓名、所持牌Card信息；
- 洗牌并向两位玩家各发两张牌；
- 比较玩家手中牌大小，得出获胜者；
3、程序实现

public class Card {
private Integer id; //牌的大小
private Integer type;//牌的花色 public Card(Integer id, Integer type) {

}
@Override
public String toString() {
return "Card [id=" + id + ", type=" + type + "]";
}
}
