Chapter 7 Basics of Object Oriented Programming

In this chapter we will discuss fundamental ideas related to object-oriented programming. In brief we will discuss these ideas:

OOP is about getting objects to collaborate with each other by asking each other to do things.
Object internals can be used to hide implementation details and expose only certain interfaces.
We break larger problems into simpler problems by assigning single responsibilities to classes and methods.
We discover new classes when we look at "clumps of behavior": methods in a big class that all use the same set of fields or parameters, or conversely a set of parameters that appears to be used together a lot.
