Foundations of Object-Oriented Programming: Classes and Objects

Transitioning from writing simple scripts to structuring robust, reusable code requires a solid understanding of Object-Oriented Programming (OOP). This text-only course guides you through the foundational building blocks of OOP, helping you think about software design in a structured, professional way. By reading through clear, written explanations and analyzing practical code snippets, you will gain the confidence to design your own custom types and manage data safely within your applications. What you'll learn: Understand the fundamental differences between classes, objects, and primitive data types; Create robust class definitions with fields, properties, and modern constructor patterns; Instantiate objects safely using the new operator and manage their state; Apply encapsulation principles to protect internal data and expose clean public interfaces; Implement modern clean-code practices for object initialization and state management. The course begins with essential terminology and the core philosophy of object-oriented design. You will then progress through step-by-step written tutorials covering class structure, constructors, and data hiding. This course is designed for beginner programmers who understand basic variables and control flow but are new to object-oriented programming. No prior OOP experience is required. Start reading today to unlock the power of structured, object-oriented software design.
