Basic Concepts of Object-Oriented Programming

Introduction

 OOPs, or Object-Oriented Programming is a programming model or paradigm which revolves around the concept of “OBJECTS”. Objects can be considered as real-world instances of entities like class, that contain some characteristics and behaviors specified in the class template.

What Is Object-Oriented Programming?

Object-Oriented Programming(OOP), is all about creating “objects”. An object is a group of interrelated variables and functions. These variables are often referred to as properties of the object and functions are referred to as the behavior of the objects. These objects provide a better and clear structure for the program.

For example, a car can be an object. If we consider the car as an object then its properties would be – its color, its model, its price, its brand, etc. And its behavior/function would be acceleration, slowing down, gear change.

Another example- If we consider a dog as an object then its properties would be- his color, his breed, his name, his weight, etc. And his behavior/function would be walking, barking, playing, etc.

What Is The Need For OOPs?

There are many reasons why OOPs is mostly preferred, but the most important among them are:

OOPs helps users to understand the software easily, although they don’t know the actual implementation. With OOPs, the readability, understandability, and maintainability of the code increase multifold. Even very big software can be easily written and managed easily using OOPs. What Are Some Major Object Oriented Programming Languages? The programming languages that use and follow the Object-Oriented Programming paradigm or OOPs, are known as Object-Oriented Programming languages. Some of the major Object-Oriented Programming languages include: Java C++ Javascript Python PHP And many more. What Are The Main Features Of OOPs? OOPs or Object Oriented Programming mainly comprises of the below four features, and make sure you don't miss any of these: Inheritance Encapsulation Polymorphism Data Abstraction Why Is OOPs So Popular? OOPs programming paradigm is considered as a better style of programming. Not only it helps in writing a complex piece of code easily, but it also allows users to handle and maintain them easily as well. Not only that, the main pillar of OOPs - Data Abstraction, Encapsulation, Inheritance, and Polymorphism, makes it easy for programmers to solve complex scenarios. As a result of these, OOPs is so popular.
