"I just finished reading HF OOA&D and I love it! My favorite thing about this book is that it focuses on why we do OOA&D to write great software!"

“Behind the hilarious illustrations and crazy fonts hides a serious, clever and extremely well-crafted presentation of OO Analysis and Design. As I read the book, I felt like I was looking over the shoulder of an expert designer who explained to me what topics were important at each step and why. "

Edward Sciore, Associate Professor, Department of Computer Science, Boston College

Tired of reading Object Oriented Analysis and Design books that only make sense once you're an expert? You've heard that OOA&D can help you write great software every time - software that gives you more time to do what makes your boss happy, your customers happy, and what makes you happy.

But how?

Head First Object Oriented Analysis and Design shows you how to analyze, design and write serious object-oriented software: software that is easy to reuse, maintain, and extend; software that doesn't give you a headache; software that allows you to add new features without breaking old ones. In it you will learn how to:

* Use OO principles such as encapsulation and authorization to build flexible applications

* Implement the Open-Closed Policy (OCP) and Single Responsibility Principle (SRP) to encourage reuse of your code
