Query: A pedagogical triumph!

This book is virtually unique. By presenting object-oriented programming from the twin viewpoints of java and c++, the author gives a 3-dimensional perspective of object-oriented programming.There are three groups of programmers who would benefit from this book. Firstly, those who have mastered an imperative language like C and who are totally new to object oriented programming. Learning both java and c++ by reading one book can save a tremendous amount of time.But two equally important audiences for this book are those programmers who know only c++ or java, and want to learn the other language. If you are either of these camps, this is the book you've been waiting for. It can be read as a "programming cookbook" showing how to do almost every common programming task, from copying files to Gui/Database programming in both java and c++, allowing the reader to leverage expertise in one language when learning the other.
