Foundations of Object-Oriented Programming (OOP)

Writing software that is scalable, reusable, and easy to maintain requires a solid grasp of how code is structured. This course introduces you to Object-Oriented Programming (OOP), the fundamental paradigm behind most modern software development. You will transition from writing simple scripts to designing robust, organized programs by thinking in terms of objects and relationships. Through clear text explanations and practical code examples, you will build a strong mental model of how to structure your applications for real-world projects. What you'll learn: - Understand the core concepts of objects, classes, and how they model real-world data - Apply the four pillars of OOP: encapsulation, inheritance, polymorphism, and abstraction - Use composition alongside inheritance to build flexible and maintainable systems - Implement modern clean code principles and type hints to make your code self-documenting - Practice translating real-world problems into structured object-oriented designs - Read and analyze object-oriented code to identify design patterns and potential improvements This course begins with essential definitions and foundational concepts before guiding you through practical design scenarios. You will read through step-by-step code walkthroughs and complete written exercises designed to reinforce your understanding. This course is designed for beginner programmers who want to move beyond basic syntax and start designing structured software. No prior experience with object-oriented design is required.
