Basic Concepts of OOP (Object-Oriented Programming)

What Is an Object in Programming?

Object-oriented programming, or OOP, is an approach to problem-solving
where all computations are carried out using objects.

An object is a component of a program that knows how to perform certain actions and how
to interact with other elements of the program.

Objects are the basic units of object-oriented programming.
A simple example of an object would be a person.

Logically, you would expect a person to have a name.

This would be considered the property of the person.

You could also expect a person to be able to do something, such as walking or driving.

This would be considered a method of the person.

Basic Concepts:

Class

• The class is a model or blueprint or prototype of an object that defines or specifies all the properties & behavior of the objects.

object

• An object is an entity or instance of a class.
• Each object has properties and behaviors.

Polymorphism

• Polymorphism refers to the ability to process objects differently depending on their data type or class.

Abstraction

• Abstraction means hiding the implementation and showing only functionality to the user.

Encapsulation

• Encapsulation is the process of binding the data by making it private and functions to process that data into a single unit.
