聚美优品商品分类
在面向对象编程中,创建商品类(Product Class)和商品类别类(Category Class)通常是为数据模型服务的。这里我将给出一个简单的基本概念:
**商品类(Product Class):**
```java
public class Product {
private int productId;
private String productName;
private String description;
private double price;
private Category category;
// 构造函数、getter和setter
public Product(int productId, String productName, String description, double price, Category category) {
this.productId = productId;
this.productName = productName;
this.description = description;
this.price = price;
this.category = category;
}
// getter 和 setter methods for each attribute
public int getProductId() { return productId; }
public void setProductId(int productId) { this.productId = productId; }
// ... similar methods for other attributes
// 如果需要,可以添加方法如displayDetails()展示商品详细信息
}
```
**商品类别类(Category Class):**
```java
public class Category {
private int categoryId;
private String categoryName;
// 类似上一个类,构造函数、getter和setter
public Category(int categoryId, String categoryName) {
this.categoryId = categoryId;
this.categoryName = categoryName;
}
// getters and setters
public int getCategoryId() { return categoryId; }
public void setCategoryId(int categoryId) { this.categoryId = categoryId; }
public String getCategoryName() { return categoryName; }
public void setCategoryName(String categoryName) { this.categoryName = categoryName; }
}
```
这两个类定义了商品和类别应有的属性,并提供了一些基本操作。实际项目中可能会根据需求增加更多的功能,比如商品库存管理、类别间的层级关系等。
