Introduction

Sams Teach Yourself Object Oriented Programming in 21 Days takes a practical approach to teaching object-oriented programming (OOP). Rather than teaching OOP at an academic level, this book presents accessible, user-friendly lessons and examples designed to let you begin applying OOP right away. Instead of trying to teach every agonizing, theoretical detail, this book highlights those topics that you need to know to be able to apply OOP to your daily projects—and not waste your time fighting some theoretical debate.

The goal of this book is to provide you with a solid foundation in object-oriented programming. After 21 days you should have a good footing in the basic concepts of OOP. Using this foundation you can begin to apply OOP concepts to your daily projects as well as continue to build your OO knowledge through additional study. You will not learn all there is to know about OOP in 21 days—that’s simply not possible. It is possible, however, to build a solid foundation and get off on the right foot. This book helps you do just that.
