OOPs Course Online: Free Courses For Object-Oriented Programming

Find the best OOPs Course online to learn Object-oriented programming using different languages like Python, Java, PHP, JavaScript. If you are someone who is new to object-oriented programming, you must know the basics before you can get started. Most of us have already learned Object-oriented programming in our college days while learning a programming language like Python, Java, or C++ but we never focused solely on the concepts of OOP but rather on the programming language itself.

As a result of this most of the programmers didn’t understand the purpose of using classes and objects and how to design them. It is important for a programmer to have a good understanding of the basic concepts of OOPs, OOP patterns, and design principles to write a rich program to solve real-world problems.

In this article, we have mentioned some of the best online OOPs courses online which you can take to learn and improve your object-oriented programming skills. But before going directly to these OOPs courses let us first understand the basics of object-oriented programming.

Introduction To Object Oriented Programming (OOPs):

Object-oriented programming (OOP) is a paradigm that allows programmers to define the data type of a data structure and the types of functions (operations) that can be applied in the structure. Thus, the data structure becomes an object which includes both data and functions.

OOPS allow you to write a program based on a real-world model in terms of objects and classes. This makes the representation of the real-world thing in programming easier as well as allow you to manage the complexity of the program. OOps also allows you to build relationships between different objects. For example, One object can inherit the characteristics of another.

Below we have mentioned some basic concepts of OOPs to help you understand better.

Abstraction: It is one of the key concepts of object-oriented programming which helps to handle the complexity in programming languages by hiding the unnecessary details from the user. This allows the user to implement the logic on top of the abstraction provided without even considering the hidden complexity.

Let’s take an example from the real-world. You wake up in the morning and want a coffee, you go into the kitchen and switch on the coffee machine and make a coffee. Here you don’t need to know how the coffee machine works internally. You just pour some water and coffee beans and turn the switch on and the work is done.

Class:  A class is a blueprint for creating objects or a particular data structure. It is a category of objects which defines the nature of a future object.

Object: Object is a self-contained module that consists of properties and methods to manipulate the data and make a particular type of data useful.

Encapsulation: It is one of the fundamental concepts which describes the idea of bundling methods and data that work as one unit. For example, class in Java. This concept is often used to hide the internal state of an object from the outside also known as information hiding.

Polymorphism: The word polymorphism means having various forms. In Object-oriented programming, it is the ability to process the objects differently depending on the type of class or data.

Inheritance: Inheritance is the process of creating new classes that are known as “derived classes”  from the existing classes or base classes. It is a mechanism in which the derived class will inherit all the capabilities of the base class.

Benefits Of Taking OOPs Course:

  • Taking a course of Object-oriented programming on your preferred language will help you build your programming skills.
  • It will help you reduce the development time as you can reuse the code and develop modules based on previous projects.
  • Objects also help to prevent accidental overwriting or influence by another program.
  • This framework also addresses the common difficulties that we face in procedural programming such as cumbersome code.
  • Using the concepts of object-oriented programming, software development becomes smoother, and the code becomes clean.
  • Big companies like Microsoft, Google uses object-oriented programming as their primary model.
  • It helps to model real-life problems.
  • It provides a simple way to solve complex problems.
  • It helps in polymorphism and relates to many objects.
  • OOP provides a clear modular structure for programs.
  • It is good for defining abstract data types.
  • It will help you implement details that are hidden from other modules.
  • You can modify and maintain your existing code as new objects which can be created by manipulating the existing old code.
