The OOP or Object Oriented Programming is a paradigm that allows you to write a program by modeling real-world things in terms of class and object. It not only make to represent a real-world thing in the programming world easier but also allow you to manage the complexity of your program.
Most of us learned object-oriented programming while learning a programming language e.g. learning Java or Python but that time our focus mostly remain on programming language rather than truly understanding OOP concepts.
That’s why many programmers end up knowing how to declare a class or instantiate an object rather than understanding the purpose of class and object and how to design one.
This is something you learn on the job, where you need to solve a real-world problem. For example, consider Udemy, one of the popular online courses platform.
If you think how Udemy should be storing courses, searching them and recommending them to a user and if you have to implement a similar solution then how would you do that? That’s where you start thinking about Course as a class and each course an instance of that Course. That’s where the definition that “A class is a blueprint to create objects” start making sense.
In short, it’s important to have a good understanding of OOP basics, OOP design principles, and OOP patterns to write a robust program to solve real-world problems.
In this article, I am going to share some of the free courses you can take to learn OOP basics or improve your object-oriented programming skills.
You can choose the course in the language you are most proficient. This will help you to focus on object-oriented programming rather than on programming language and its syntax.
This is a free course to learn object-oriented programming in Java from Udemy.
It will introduce you to some of the essential OOP concepts in Java e.g. class, objects, inheritance, polymorphism, abstraction, encapsulation, and association, composition, etc.
You will learn how to use these object-oriented programming concepts in code examples, discover how these concepts are used in real-world applications that require user input and understand the benefits of mastering these concepts in Java.

By the end of this course, you will create your own game (one of the best way to improve your OOP skill), understand how and when to apply foundational Java concepts, and will gain a deeper understanding of the tools and logic that professional Java developers use every day
2. Python: OOP [Free Udemy Course]
This is another free course to learn Object-Oriented programming in Python from Udemy.
The course will not only teach you how to structure your code using class and object but also how to do object-oriented programming by bundling attributes and methods within a class.
You also will learn about the four pillars that hold together the object-oriented programming, which are:
This course covers all of them in good detail with some real-world examples. At the end of this course, you will be able to write your own object-oriented programs in Python!
This is another free course to learn Object Oritend basics from Udemy but with C#. If you are a C# developer then you can use this course to learn object-oriented programming.
This course will lay the foundations of Object-Oriented Programming (OOP) in your mind, allowing you to progress to more complex, systematic and cleaner Programming methods.

The course is aimed at students who have at least some coding experience, preferably with C# (but Java or any other similar language is also acceptable).
Finally, you will build a Project “Warrior Wars!” to practice your object-oriented programming skill.
The course starts by covering simple OOP concepts such as classes, objects, methods, properties, MVC, Functions, Data Abstraction, Data Binding, etc.
This is a great course to learn object-oriented design principles, which is also an important part of learning Object-oriented programming.
This course introduces foundational principles of creating a well-crafted code and is appropriate for anyone hoping to improve as a developer.
The SOLID principles are coined by Uncle Bob on his classic book Clean Code (a must-read books for any Java program if you haven’t read it yet then read it now) and they are fundamental to designing maintainable and robust OOP applications.
Whether you’ve only just begun writing software or have been doing so for years, these principles, when used appropriately, can improve the encapsulation and coupling of your application, making it more manageable and testable in the face of changing requirements.
In this course, Master Object-Oriented programming Concepts, you review the basics of objects and classes covered in their previous courses.
The best part of this course is that you will learn OOP by typing and doing things. You will be given instructions like how to create a Bike Constructor on lines 7 that has no properties and then you need to write code and submit it to compilation.
This learn-by-doing approach makes sure that whatever you are learning is actually going into your head.
The course uses Java Programming language. So if you want to learn object-oriented programming using Java, this is the best course for you.
This is an awesome course to learn Object-Oriented Programming in Java on Coursera, one of the leading online learning portals which bring course materials from ivy league universities like Yale, Stanford, University of Michigan and others.
Like any Coursera courses, it is also free-to-audit, which means you can join it for free but you need to pay if you need certification. This means its completely free if you just want to learn OOP with Java.
This course is also part of multiple Specializations or Professional Certificates programs. Completing this course will count towards your learning in any of the following programs:
- Object-Oriented Programming in Java Specialization by Duke University
- Object-Oriented Java Programming: Data Structures and Beyond Specialization by UCSanDiego
