Case Study $2$: Online Retail Store

Background: An online retail store wants to develop a new software system to handle its

operations. This system will manage products, orders, customers, and inventory. The system

must support different types of products, including electronics, clothing, and groceries.

Requirements:

The system should have different product categories, each with specific attributes. For

example, electronics have a warranty period, clothing has sizes and materials, and

groceries have an expiration date.

Customers can place orders for multiple products. Each order should track the order

date, delivery date, and status.

The system should handle inventory management, including updating stock levels

when orders are placed and returned.

Implement a simplified version of the system focusing on class structures, inheritance,

and method overloading.

Tasks:

Design and implement the classes for the online retail store, including Product,

Electronic, Clothing, Grocery, Customer, Order, and Inventory. Utilize inheritance and

method overloading where appropriate.

Implement a method in the Order class to calculate the total cost of an order,

considering any discounts for bulk purchases.

Questions:

Class Design and Method Overloading:

Implement the class hierarchy for the online retail store. Ensure that the

Product class is abstract and that Electronic, Clothing, and Grocery classes

inherit from it$.$ Each class should have appropriate properties and methods.
