What are the basic pillars of OOPS?

@weston_dietrich Fundamental pillars of OOPS and are as follows:

Abstraction

Hiding the sensitive data or the way of implementation, but revealing the necessary data to the end user.It limits the scope of variables, methods.Abstraction is to implement the security features in OOPS and so in application.

Encapsulation

Encapsulation is the wrapping of data and data functions in a single block of codes. It contains the data definitions and behavior definition in a single block that is Class.

Inheritance

Inheritance provides flexibility features to OOPS. It allows a class to share its functions, variables to other classes and the classes that will be using the functions definitions and data variables of other class called child class, and this phenomenon is called Inheritance.

Polymorphism

Polymorphism is a way to re-implement the methods in child-class or in a subclass that is already implemented in the parent class.It gives flexibility to an object to represent it and to use its many forms as per the function definitions in classes.
