Case Study

$2$

: Online Retail StoreBackground: 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:

$1$

$.$

$$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

$.$

$2$

$.$

$$Customers can place orders for multiple products. Each order should track the order date, delivery date, and status

$.$

$3$

$.$

$$The system should handle inventory management, including updating stock levels when orders are placed and returned

$.$

$4$

$.$

$$Implement a simplified version of the system focusing on class structures, inheritance, and method overloading.Tasks:

$1$

$.$

$$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

$.$

$2$

$.$

$$Implement a method in the Order class to calculate the total cost of an order, considering any discounts for bulk purchases.Questions:

$1$

$.$

$$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. Write overloaded constructors for the Order class to support creating an order with different initial parameters

$$Inventory Management and Order Processing: Implement a method in the Inventory class to update stock levels when an Order is placed. Demonstrate this functionality with a sample implementation. Write a method in the Order class to process returns and update the inventory accordingly. Ensure that the method handles different types of products correctly
