Upon reviewing the list of top programming languages, we discovered that object oriented programming languages (OOP) comprised the majority of entries.
I’ve noticed that many programmers prefer using Object oriented programming languages to create complex apps since it makes it simple to add or modify features without altering the existing code. Moreover, these languages provide quicker and less expensive development and maintenance.
Let’s go over the fundamentals to understand why object-oriented programming (OOP) is the best choice for your next project!
Basically, there are two types of programming languages: high-level and low-level. Machine-understandable languages are known as low-level languages, and human-language-like, user-friendly languages are known as high-level languages.
An Object-oriented programming language is a high-level language. This kind of programming involves creating objects within a program that can communicate with the user, objects, or other programs. As a result, programs become easier and more efficient.
When code reuse and upkeep are top priorities, these languages should be used since they facilitate development and allow us to add code easily without interfering with other code blocks. Besides this, the best use cases of OOP are:
When managing large, complex systems with interrelated components.
To create modular code that can be reused and extended.
To model real-world entities and their interactions effectively.
When working in teams, for clear structure and collaboration.
When building scalable applications that require extensibility.
To facilitate easier bug tracking and feature addition.
Simula (1967) introduced information hiding to ALGOL, marking the beginning of OOP. However, Java has been one of the most popular object oriented programming languages since the 1990s.
In this article, we will cover the top 10 object oriented programming languages in 2024. But first, let’s find out exactly what this type of programming is and what object-oriented programming language is!

What is Object Oriented Programming & Object Oriented Programming Languages?
The terms “object” and “oriented” are combined to form the term object-oriented.
As we all know, an object is an item or thing that exists in the actual world. They may have characteristics and functions. Consider an item such as a watch. There are attributes to that watch, such as its specific weight and color, and it is made of metal.
Oriented means having a focus on a specific type of object or entity.
A programming paradigm called object oriented programming, or OOP, is focused on specific objects or data. OOP enables programmers to approach variables, data structures, and functions as “objects” that interact with one another rather than as sequential instructions as in procedural programming.
According to leading front-end development companies, OOP is often the best option for manufacturing and designing applications. It enables us to divide the program into manageable bits so that we may address one item at a time.
Languages that support object-oriented programming (OOP) are called object oriented programming languages. These languages allow developers to organize software into objects that combine behavior and data. These languages use object oriented concepts to facilitate modularity, maintainability, and code reuse.
Understanding and applying object-oriented programming requires an understanding of the few fundamental concepts called the pillar of OOP. Let’s cover those key concepts.
Key Concepts of Object Oriented Programming
To fully comprehend the OOP programming, it is advised to delve deeper into each of the essential components as listed below:
Classes
A class is a sort of user-defined data that serves as the model for different objects, properties, and functions. It represents the collection of attributes or operations shared by all objects of a certain kind. It is among the most essential principles of OOP.
Example- A Book class defines a book’s properties (e.g., title, author) and the actions it can perform.
Objects
It is a foundational piece of OOP that symbolizes actual entities. The description is the first object to be defined when a class is created. An object contains an instance of a class.
Example- In the library system, each individual book, like “Harry Potter” or “The Great Gatsby,” is an object created from the Book class.
Methods
Methods are functions defined within a class that describe the behavior of objects. They can operate on the attributes of the object and perform various actions. It represents an object’s actions and is defined inside a class. A reference to an instance object is used at the beginning of each method in class declarations. Methods give an account of how a thing behaves.
Example- In the Book class, a method like display_info would provide information about the book, such as its title and author.
Attributes
Attributes are variables defined within a class that hold the data or state of an object. They serve as a representation of the object’s attributes. In other words, we can say that these attributes serve to differentiate across various classes. Class attributes are defined in the class template and are specific to the class.
Example- The title, author, and pages are attributes that store data about the specific book my_book.
Principles of Object Oriented Programming
OOP is based on four fundamental principles that guide the design and organization of software. These principles are:
1. Encapsulation
One of the four pillars of OOP is encapsulation. It is the process of combining functionality (methods) that manipulate data with data (attributes) into a single unit or class. This mechanism is essential for protecting data integrity since it prevents external access to an object’s internal workings and prevents developers or other software components from changing them.
Example: In a Book class, the title, author, and pages might be private attributes (accessible only within the class), and you would provide public methods to get or set these values.
2. Abstraction
Abstraction is the process of displaying only an object’s essential properties while concealing complex implementation details. For instance, a function could be abstracted to become its own entity if a programmer writes the same function repeatedly for different objects.
It frees the users from having to comprehend an object’s inner workings in order to engage with it at a higher level. Over time, this idea can make it easier for developers to add or modify new features.
Example: When you use a method like get_title() from the Book class, you don’t need to know how the title is stored internally; you just know that the method will return the title.
3. Inheritance
With inheritance, programmers can construct new classes from existing ones (parent classes), referred to as subclasses or child classes. This decreases development time and guarantees a greater degree of precision. Classes can reuse code and properties from other classes. Developers can reuse similar functionality by assigning relationships and subclasses between items while maintaining a distinct hierarchy.
Example: Suppose you have a base class, Book, and want to create a specialized class called EBook with additional attributes like file format and file size.
4. Polymorphism
In OOP, polymorphism refers to the ability to “take more than one shape.” It describes the capacity to treat things differently based on their nature. Polymorphism enables us to specify various object handling techniques according to the object’s derived class. Additionally, it permits using a single interface for a broad category of actions. The exact nature of the situation determines the specific action.
Example: Suppose both Book and EBook classes have a method read(). Polymorphism allows you to use the same method name for different types of books, but each will have its own implementation.
Advantages of Object Oriented Programming: Why OOP Matters?
Object-oriented programming (OOP) offers several key benefits that make it a popular paradigm in software development. Here are some of the primary advantages:
This programming breaks down code into discrete objects and classes, making it easier to manage and understand.
It promotes code reuse by allowing classes to be used across different programs and projects.
It combines data and methods within objects, protecting the internal state and exposing only necessary functionalities.
It enables new classes to inherit attributes and methods from existing classes, fostering code reuse and reducing redundancy.
It simplifies updates and bug fixes by isolating changes to specific modules.
It facilitates the development of scalable systems by allowing for easy extension and integration of new features.
It allows objects to be treated as instances of their parent class, with methods behaving differently based on the actual object type, enhancing flexibility.
It hides complex implementation details behind a simple interface, allowing developers to work with higher-level concepts.

1. How is an object-based programming language different from an object oriented programming language?
Object-based programming languages support objects and encapsulation but lack full OOP features like inheritance and polymorphism. In contrast, object oriented programming languages offer a complete OOP model, including encapsulation, inheritance, and polymorphism, enabling more robust and flexible code structures.
2. What is the difference between procedural and object oriented programming?
Procedural programming focuses on functions and sequences of instructions, while OOP centers around objects and classes, emphasizing data encapsulation, inheritance, and polymorphism. OOP promotes modularity and code reuse, whereas procedural programming is more linear and function-driven.
3. Functional vs Object-oriented programming: Which is better?
Choosing between functional and object-oriented programming depends on the project. Functional programming excels in immutability and statelessness, enhancing predictability and concurrency. Object-oriented programming offers robust data modeling and modularity through objects and inheritance. The “better” approach depends on specific project needs and team expertise.
4. Which are the best object oriented programming languages for developing mobile apps?
For mobile app development, the top object oriented programming languages include Java and Kotlin for Android and Swift for iOS. These languages offer robust OOP features and are well-supported, with extensive libraries and frameworks tailored to them.
