One of the easiest ways to understand what is meant by ‘object oriented’, is to define what it is not. Before Object Oriented Programming (OOP) programs were written an imperative way ...

In class-based object-oriented programming, a supertype is a class that another class descends from. In OOP-speak, we say the subclass inherits from the superclass.

In making the transition from a structured language to an object-oriented language, a software engineer must understand the concept of data abstraction and encapsulation. This, I believe, is the ...

Proponents of object-oriented techniques point to the flexibility and extensibility of object-oriented systems along with other benefits such as increased modularity, abstraction, and encapsulation.

This lesson starts a new segment about Object-Oriented Programming (OOP) — an important set of concepts critical to understanding any modern software, not just modern embedded software. As usual in ...

Classes, fields, methods, constructors, and objects are the building blocks of object-based Java applications. This Java tutorial teaches you how to declare classes, describe attributes via fields ...

Moving from object-oriented to functional programming is a paradigm shift for developers, but these key principles explain why it's worth the effort. ... In functional programming, functions are ...
