Object-Oriented Programming — What’s It All About?

IN THIS CHAPTER

Reviewing the basics of object-oriented programming

Getting a handle on abstraction and classification

Understanding why object-oriented programming is important

This chapter answers two essential questions: “What are the concepts behind object-oriented programming, and how do they differ from the procedural concepts covered in Book 1?” You begin by considering the abstraction that object orientation offers to help create a real-world model in code.
