Head First Object-Oriented Analysis and Design: A Brain Friendly Guide to OOA&D

Head first series are simply a gem and so is this book. When I started reading the book, I simply lost with vague examples and did not find useful. But then I got some drill questions which made me to read this book again and I started to make sense. Though examples are not real scenarios but focus on concepts that are described such as how to take the information and apply oops , which parameters to use , when to encapsulate and so on.
