Class and Object Definition: Encapsulation, Inheritance, and Polymorphism of Object-Oriented Concepts in 22 Languages

Ever wondered how object-oriented concepts like encapsulation, inheritance, and polymorphism are implemented across radically different programming languages?

Class and Object Definition: Encapsulation, Inheritance, and Polymorphism of Object-Oriented Concepts in 22 Languages offers a wide-reaching exploration of how object-oriented programming (OOP) is structured, extended, and leveraged across today’s diverse software ecosystems—from Ada and Rust to Haskell, Python, and XSLT.

Through 6 parts and 24 accessible modules, this book compares class structures, memory models, inheritance chains, access control, dynamic dispatch, and even metaclasses and reflection. Whether you're interested in deep class hierarchies, interface contracts, or polymorphic flexibility, this book breaks each topic down with instructional clarity and real-world comparisons—perfect for developers, educators, and curious architects.

Designed in a technical-informal tone to make complex concepts digestible, this guide helps you write clearer, more interoperable object-oriented code across statically and dynamically typed languages. If you want to understand not just how to write classes, but how they behave and evolve across languages—this is your next essential read.
