This text investigates the fundamental principles of object-oriented programming by abstracting core concepts away from the syntax of specific programming languages. Timothy Budd, a recognized educator in computer science, utilizes a comparative approach to demonstrate how concepts like inheritance, polymorphism, and encapsulation function across diverse environments. By analyzing multiple languages, the book establishes a conceptual framework that allows students to understand the underlying logic of object-oriented design regardless of the specific implementation language used.

Experts frequently cite this work as a foundational text for students seeking to understand the theoretical underpinnings of object-oriented programming. Readers often note that the comparative approach provides a clear perspective on how different languages handle similar design challenges.
