JAVA collection集合之撲克牌遊戲實例

Collection 層次結構中的根介面。 Collection表示一組對象,這些物件也稱為collection的元素。有些 collection 允許有重複的元素,而有些則不允許。有些 collection 是有序的,而有些則是無序的。 JDK 不提供此介面的任何直接 實作:它提供更具體的子介面(如 Set 和 List)實作。此介面通常用來傳遞 collection,並在需要最大普遍性的地方操作這些 collection。

主要內容:這裡使用collection集合,模擬香港電影中大佬們玩的撲克牌遊戲。

1、遊戲規則:兩個玩家每人手中發兩張牌,進行比較。比較每位玩家手中牌最大的點數,大小由A-2,點數大者獲勝。若點數相同,則比較花色,大小由黑(4)、紅(3)、梅(2)、方(1),花色大者獲勝。

2、實現步驟:

創建一副撲克牌A-2,四種花色黑(4)、紅(3)、梅(2)、方(1)共52張牌;
創建兩個玩家包含玩家ID和姓名、所持牌Card資訊;
洗牌並向兩位玩家各發兩張牌;
比較玩家手中牌大小,得出獲勝者;

3、程式實現

牌Card類:包含牌的數字和花色

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