Object-Oriented Programming in D: Building Inheritance Hierarchies

Object-oriented programming is a cornerstone of robust software design, but mastering how classes interact in the D programming language requires a solid grasp of its unique inheritance model. This text-based course guides you through designing clean, reusable, and type-safe hierarchies using D's modern OOP features. Through clear written explanations and practical code challenges, you will transition from writing basic procedural code to structuring complex applications with abstract classes, overridden methods, and interfaces. You will learn how to leverage D's powerful compiler checks to enforce correct implementation behaviors across your codebase. What you'll learn: - Understand core inheritance concepts and class hierarchies in the D language - Design abstract classes and define abstract methods to establish strict contracts - Implement and override base class methods using the override keyword correctly - Utilize interfaces to achieve multiple inheritance of design in D - Apply modern D attributes like @safe, pure, and nothrow to overridden methods - Practice structuring real-world domain models through written code exercises The course begins with foundational concepts of classes and object creation in D before advancing to inheritance, abstract structures, and polymorphic behavior. You will progress through structured written examples that demonstrate how to organize code for maximum reusability and maintainability. This course is designed for beginning to intermediate developers who want to deepen their understanding of object-oriented design specifically within the D programming language. Basic familiarity with general programming concepts is helpful, but no advanced D experience is required.
