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.
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.
You can choose the course according to your preferred programming language. This will help you focus more on object-oriented programming rather than learning another programming language first.
This is a free OOPs course from Udemy which you can take to learn object-oriented programming in Java. It will introduce you to some of the topics mentioned below:
In this course, you will learn some of the essential concepts of object-oriented programming and live code examples. You will go through the real-world applications which require user input and further mastering the concepts in Java.
This is a free OOPs course from Udacity where you can learn object-oriented programming in Java. It will introduce you to some of the basic concepts of OOPs such as class, objects, inheritance, Collections, etc.
While taking this course you will use object-oriented programming concepts in your coding.
LESSON 1: The World of Objects
LESSON 2: User Interaction
LESSON 3: Inheritance
LESSON 4: Collections
This is another OOPs course from Udemy where you can learn Object-Oriented programming in Python. This course will teach you how to structure code using objects and classes and how to do object-oriented programming by bundling methods and attributes within a class.
Through this course, you will get 8 patterns that all the big software companies utilize to deliver their products. This course is presented in a very unique way giving you deep insights on software engineering in an engaging way.
This course will introduce you to the 8 main patterns mentioned below:
You will also learn the four pillar of object-oriented programming:
This is another OOPs course from Udemy where you will learn Object Oriented basics in C#. If you are a C# learner or a C# developer then you can enroll in this course to learn object-oriented programming.
This is a great course that you can take to learn the principles of object-oriented design. This course will give an overview of the basic foundational principles of creating well-crafted code and it is appropriate for anyone who is hoping to improve as a developer.
This course is coined by Uncle Bob in his book Clean Code (a must-read book for any Java learner). The principals provided in this course, when used properly can improve the coupling and encapsulation of your application.
Most of the online courses now provide certification of completion too. Taking these OOPs Courses mentioned above will provide you high-level programming skills in your preferred language.
