Did you know Object oriented programming (OOP) has been around for over 50 years?
🤓 Fun fact: Simula is the world’s first object-oriented programming language, introducing us to objects, classes, and other OOP goodness.
Today, OOP is used everywhere: software apps, websites, mobile apps, and more.
It’s a good skill to have as a software developer.
So today we’re showing you the top 10 best object-oriented programming books for 2021.

TLDR: Top 10 Best Object-Oriented Programming Books
Object-oriented programming (OOP) is a programming paradigm that creates objects within code. These objects contain functions and data.
We picked the best of the best object-oriented programming books.
💥 Best Value 💥
Head First: Object-Oriented Analysis and Design
💥 Best for New Programmers 💥
Beginning Java Programming: The Object-Oriented Approach
What is object-oriented programming?
Object-oriented programming (OOP) is a programming paradigm. It creates objects within code that contain functions and data.
OOP binds the data and functions together.
No other parts of the code can access that data except that function.
These objects are reusable.
Now that we have that out of the way – here are the best object-oriented programming books for 2021.
With in-depth tutorials, Programming Python covers application domains in system administration, graphical user interfaces and the Web.
In addition, you’ll learn about how Python is used in:
- text processing
Also, Programming Python examines frequently used Python tools and libraries.
But beware, this book is massive.
It’s 1557 pages broken down into 5 sections:
- The Beginning – OOP classes, behavior, inheritance, refactoring
- System Programming – script execution, parallel system tools, file and directory tools
- GUI Programming – tkinter, coding techniques, programs
- Internet Programming – network scripting, client-side scripting, PyMailCGI server
- Tools and Techniques – databases and persistence, data structures, Python/C integration
You should understand Python fundamentals before reading this book.
First and foremost, PHP Advanced is focused on using PHP in real-world applications.
So you’ll learn how to build web applications using advanced PHP.
However, there’s an added section on OOP, which is what we really care about!
First, you’ll start with basic OOP fundamentals such as:
- defining a class
- creating an object
- designing classes with UML
- creating constructors and destructors
Then, the book touches on more advanced OOP concepts like:
- inheriting classes
- access control
- type hinting
Finally, Advanced PHP proceeds to cover more PHP concepts.
So in all, there are approximately 100 pages dedicated to OOP.

Head First: Object-Oriented Analysis & Design shows readers how to analyze and design object-oriented software.
So that means creating software that’s reusable, maintainable and extendable.
In addition, you’ll be able to add new features without breaking existing ones.
Also, you’ll learn how to build flexible applications using object-oriented principles such as delegation and encapsulation.
Then, you’ll learn how to use OOP design patterns to solve problems more efficiently.
Finally you’ll learn about:
- gathering requirements
- design principles
- iterating and testing
🔥 Geena’s Hot Take
Whenever I get the chance, I will always recommend a Head First book.
These books are rad!
It’s so easy for programming books to be dull walls of text. Heck, a lot of them are.
But not Head First.
They speak in layman’s terms, plain English.
In addition, they write a ton of notes down and pair them with swaths of imagery to drive concepts home.
So it’s kind of like they clarify something, then clarify the clarification.
This is especially helpful with difficult concepts such as OOP.
🔥 Pick up Head First: Object-Oriented Analysis and Design. 🔥
First, the book starts off with a refresher on objects.
Then you’ll go through some OOP essentials like abstraction, encapsulation and inheritance.
So from there, you’ll move onto more complex concepts like defining contracts with duck typing.
In addition, you’ll cover advanced object creation and SOLID principles.
Also, some other core concepts you’ll learn include:
- identifying and applying common patterns
- build robust and maintainable code
- use modular architecture to design applications

Using practical examples, Mastering Object-Oriented Python teaches advanced OOP concepts in Python.
So you’ll learn how to create Python programs using design alternatives.
Then, you’ll learn how to handle object conversions, hashing and object comparison.
In addition, you’ll learn how to locate the best algorithms and data structures.
Finally, you’ll learn how to implement object-oriented designs in your programs.
So here are some specifics you’ll learn:
- examine design patterns for
- how to use Flask
- use SOLID principles
- create classes
- design testable code
And much more.
You should have a solid Python background before reading this book. In addition, you should have prior knowledge of OOP design patterns and concepts.
🔥 Pick up Mastering Object-Oriented Python. 🔥
In Modern Programming, you’ll learn how to break down OOP into its core building blocks.
Then, you’ll learn how to build efficient and maintainable programs.
Also, you’ll learn how to use tools like an integrated development environment (IDE).
Finally, you’ll learn how to work with other developers.
Modern Programming also covers:
- critical analysis
Also much more.
While this book caters to experienced programmers, there are a lot of good bits for beginners too (teamwork, IDEs, etc.).
In Python 3 Object-Oriented Programming, you’ll first learn syntax and libraries for Python 3.8.
In addition, you’ll learn about data encapsulation, classes and exceptions. Then you’ll learn when to use each of them.
Therefore, by studying high-level design patterns, you’ll learn how to create maintainable applications.
Also, Python 3 Object-Oriented Programming covers:
- when objects are alike
- when to use OOP
- Python data structures
- strings and serialization
- Python design patterns
And much, much more.
This book is for developers who are completely new to object-oriented programming. It’s also suitable for devs who have a basic understanding of Python 3 concepts.
🔥 Pick up Python 3 Object Oriented Programming. 🔥
Beginning Java Programming teaches Java using an object-oriented approach.
Therefore, you’ll learn OOP in Java right off the bat.

Then you’ll make apps accessible to graphical user interface (GUI) users.
OOP is covered in about half of the book. You’ll also learn about setting up your dev environment, Java fundamentals and beyond.
Some core OOP concepts covered include:
- classes and objects
- variables and methods
- class inheritance
- information hiding
- and more
In addition, every chapter uses real-world exercises based on educational and business scenarios.
This book is for programmers with no Java experience.
It covers the principles of OOP with detailed examples and breakdown on steps in explaining the code.– Beginner, Amazon Customer

- What are the best object-oriented programming books?
There are many excellent object-oriented programming books. But a big part of choosing a book is how you learn best. For example, do you thrive while reading textbooks? Then Programming Python: Powerful Object-Oriented Programming and its 1557 pages might be best for you. But if you prefer reading books that feel like the author is talking to you on a personal level, Head First: Object-Oriented Analysis and Design. It's filled with illustrations and notes to reinforce concepts.
- What is the first object-oriented programming language?
The first object-oriented programming language is Simula. Simula was developed in the mid 1960s by Norwegian computer engineers. It was the first language to use objects, classes, subclasses and inheritance. Simula 67 was another version of Simula. You'll find Simula-type objects in C++, Java and other modern programming languages.
