99 Bottles of OOP is a practical guide to writing cost-effective, maintainable, and pleasing object-oriented code.

Now available in JavaScript, PHP, and Ruby!

It explores:

• Recognizing when code is “good enough”
• Getting the best value from Test-Driven Development (TDD)
• Doing proper refactoring, not random “rehacktoring”
• Locating concepts buried in code
• Finding names that convey deeper meaning
• Safely altering code by following the “Flocking Rules”
• Simplifying new additions with the Open/Closed Principle
• Avoiding conditionals by obeying the Liskov Substitution Principle
• Making targeted improvements by reducing Code Smells
• Improving changeability with polymorphism
• Manufacturing role-playing objects using Factories
• Hedging against uncertainty by loosening coupling
• Developing a programming aesthetic

What Makes It Unique?

We are practical people. We love beautiful code but we’re committed to getting things done. 99 Bottles of OOP enables both of these desires. It teaches practical techniques for getting things done that lead, naturally and inevitably, to beautiful code.

This book contains an extended refactoring, and it details the rationale behind every change. It is a hands-on workbook rather than a list of theoretical ideas. It explains how to use the principles of object-oriented design to guide, not just the final arrangement of code, but each decision about what line of code to write next.

It teaches the theory of what good OO looks like, but even better, it supplies step-by-step guidance about how to achieve it.

Who Should Read It?

The lessons work for programmers with a broad range of experience, from rank novice to grizzled veteran. Regardless of your background or preferred programming language, 99 Bottles of OOP will teach you techniques to make your code easier to understand, simpler to change, and more satisfying to contemplate.

What’s new in the 2nd Edition?

The 2nd Edition contains 3 new chapters and is about 50% longer than the 1st. Also, because 99 Bottles of OOP is about object-oriented design in general rather than any specific language, this time around we created separate books that are technically identical, but use different programming languages for the examples.
