OOD-Blueprints: Practical Object-Oriented Design in Java

Overview

This project showcases Object-Oriented Design (OOD) principles through practical Java implementations. It is structured into multiple problems, each modeling real-world entities using encapsulation, inheritance, polymorphism, and design patterns.

Features

• Modular Codebase: Divided into distinct packages (problem1, problem2, problem3), each tackling a unique OOD challenge.
• Encapsulation & Abstraction: Secure handling of user credentials and financial data.
• Separation of Concerns: Each entity has a clear, single responsibility.
• Test-Driven Development (TDD): Includes JUnit test cases for validation.
