Foundations of Object-Oriented Programming in C++, Java, and Python

Understanding how to structure code is the key to writing scalable, maintainable software. Object-Oriented Programming (OOP) is the industry-standard paradigm that helps developers organize complex systems into manageable, reusable components. This written course guides you through the fundamental concepts of OOP, demonstrating how they are implemented across three major languages: C++, Java, and Python. By studying clear explanations and text-based code examples, you will transition from writing simple scripts to designing robust, modular applications. What you'll learn: - Understand the core pillars of OOP: encapsulation, inheritance, polymorphism, and abstraction. - Create reusable classes and objects across C++, Java, and Python. - Apply modern development practices, including type hinting in Python and clean resource management. - Design flexible class structures and learn when to favor composition over inheritance. - Implement interfaces and abstract classes to build decoupled, maintainable architectures. You will start with basic terminology and foundational definitions before diving into side-by-side language comparisons and written conceptual exercises. The material progresses logically from single-class designs to complex multi-object relationships. This course is designed for beginner programmers who know basic coding syntax and want to master software design principles. No prior OOP experience is required.
