Object Oriented Programming is a programming design paradigm in which code architectures are based on the concept of "objects". It give codes a structure, encapsulated into classes and treated as an independent, inheritable, and extendable entity, similar to how we humans structure our everyday life.

OO design principles relies on its four pillars: Encapsulation, Abstraction, Polymorphism, and Inheritance.1

For instance, a code implementation for storing different classifications of musical instruments. A family of String instruments are encapsulated by StringInstrument class where Guitar, Violin, or Cello classes inherits from. Similarly, PercussionInstrument class parents the subclasses Drums, Marimba, or Tambourine.
