Write object-oriented code that’s manageable, maintainable, and future-proof.

Inside Simple Object-Oriented Design you’ll discover insightful principles for reducing complexity in your object-oriented code, including:

• Designing classes that are always in consistent states
• Creating abstractions that make it easy to extend software in highly flexible ways
• Lessening the impact of coupling on your codebase
• Modeling class designs that abstract away infrastructure details and use your infrastructure to its maximum capacity
• Reducing the complexity of your code

Simple Object-Oriented Design: Create clean, maintainable applications is a comprehensive handbook of design practices, principles, and patterns that help simplify object-oriented software. The book is aimed at the working developer. There’s no perfection-chasing classroom theory that fails in practice—you’ll master “good enough” techniques that are effective in real-world environments.

Purchase of the print book includes a free eBook in PDF, Kindle, and ePub formats from Manning Publications.

About the technology

As your software grows and expands, every new feature and functionality potentially adds complexity to your codebase. The result? Bugs, crashes, and too much time spent detangling incomprehensible legacy code. Properly applied design principles help you ensure your applications are easy to manage for the long term.

About the book

Simple Object-Oriented Design is full of techniques to keep your object-oriented code simple even as your applications evolve and grow. Each principle in this book has been tested and proven in author Mauricio Aniche’s 20-year career in software development. You’ll learn what constitutes both good and bad object-oriented software design, and how to manage dependency, modules, and other features that give rise to complexity. Discover how to make better trade-offs in design decisions, and when to embrace complexity over simpler data structures. With this book as your vital reference, you’ll be ready to write code that’s flexible for the future without slowing feature delivery to a crawl.

About the reader

For readers who know an object-oriented language. This book’s Java examples are easy to understand for any developer.
