JAVA collection集合之 扑克牌游戏

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

牌Card类：包含牌的数字和花色

package collectiontest.games;
public class Card {
    private Integer id; //牌的大小
    private Integer type;//牌的花色
    
    public Card(Integer id, Integer type) {
        this.id = id;
        this.type = type;
    }
    public Integer getId() {
        return id;
    }
    public void setId(Integer id) {
        this.id = id;
    }
    public Integer getType() {
        return type;
    }
    public void setType(Integer type) {
        this.type = type;
