In order to really start thinking about how to properly implement OO code, it is critically important to know what data goes together with which operations—this consists of defining objects, their data, and operations.

Cedric Evans contributed greatly to the discussion with his "The Subject of Self-Consciousness" in So maintaining a large codebase like this for years — with changes along the way — is difficult.

It should only reveal operations relevant for the other objects. At this point, everything else pretty much comes as a byproduct of the other two core concept just mentioned: Much cleaner and easier to maintain.

I could keep going, but just not worthy of my time. When do you choose functional programming over object oriented? When you anticipate a different kind of software evolution: Object-oriented languages are good when you have a fixed set of operations on things, and as your code evolves, you primarily add new lietuvosstumbrai.com can be accomplished by adding new classes which implement existing methods, and the existing classes are left alone.

Object-oriented programming (OOP) is a programming paradigm that represents the concept of "objects" that have data fields (attributes that describe the object) and associated procedures known as methods.
