Hi @Sahil_Siddiqui !!
To incorporate variations in products such as different colors, sizes, or storage capacities within specific categories like phones or clothing, you can extend the existing classes with new classes representing these variations. Below is an example of how you can extend the existing classes in the provided content for the Amazon Online Shopping System:

  1. For Product Class Variation:
    You can create a subclass, say PhoneProduct or ClothingProduct, that extends the Product class and includes attributes like RAM, storage, color, size, and other specific attributes for the respective category. Here’s an illustration:
public class PhoneProduct extends Product {
    private String RAM;
    private String storage;
    private String color;
    // other attributes specific to phones

    // Constructors, getters, and setters specific to PhoneProduct
}

public class ClothingProduct extends Product {
    private String size;
    private String color;
    // other attributes specific to clothing

    // Constructors, getters, and setters specific to ClothingProduct
}
  1. For Product Variation within a Category:
    You can create subclasses for each type of product variation, for instance, PhoneRAMVariation, PhoneStorageVariation, PhoneColorVariation for the ‘Phone’ category. Similarly, for clothing, you can have ClothingSizeVariation and ClothingColorVariation. Here’s an example:
public class PhoneRAMVariation {
    private String RAM;
    private double price;
    // other attributes

    // Constructors, getters, and setters
}

public class PhoneStorageVariation {
    private String storage;
    private double price;
    // other attributes

    // Constructors, getters, and setters
}

// Similarly, create classes for PhoneColorVariation, ClothingSizeVariation, and ClothingColorVariation.

By using this approach, you can ensure that the product categories are extended to accommodate variations specific to each product type. Additionally, these variations can be managed and associated with the parent product accordingly.

By extending the classes and incorporating variations, you can maintain the structure and functionality of the Amazon Online Shopping System while allowing for different product attributes based on their specific categories.
I hope it helps.Happy Learning :blush:
