E-commerceProject (OOP)

A comprehensive e-commerce backend simulation developed in Java, focusing on Object-Oriented Programming (OOP) principles.

Overview

This project simulates the core functionalities of an e-commerce platform, including user management, product inventory, and order processing.

Key Features

• Encapsulation: All data fields are private, accessed through controlled getters and setters.
• Dynamic Inventory Management: Automatically reduces product stocks upon successful orders and prevents orders if stock is insufficient.
• Security & Masking: Credit card numbers are masked (showing only the last 4 digits) in order summaries for privacy.
• Duplicate Prevention: An intelligent "Favorite" system that prevents adding the same product multiple times.
• Relational Logic: Demonstrates complex relationships between User, Product, CreditCard, and Order objects.

System Architecture(UML)

The system is built on a modular structure consisting of 4 main classes and a comprehensive test suite:

• User: Manages profile, order history, and favorite lists.
• Product: Handles item details and stock queries.
• Order: Manages the transaction logic between users and products.
• CreditCard: Stores payment information securely.

Test Scenarios

The Test.java class includes 24 distinct test cases, covering:

• Successful order placement and stock reduction.
• Order cancellation by user input.
• Handling out-of-stock errors.
• Profile viewing with masked credit card details.
