What will I learn?
This OOP Course uses a library management system to teach practical object-oriented design with classes, inheritance, interfaces, and polymorphism. You will model users, items, and loans, apply encapsulation, validation, and state handling, and implement patterns like Strategy and Factory. With concise code examples, tests, and a final design checklist, you quickly gain skills to build clean, extensible applications.
