Top 6 Object-Oriented Programming Languages in 2021

Top Object-Oriented Programming Languages

If you are only beginning your journey as a software developer, it may be tricky to choose between the variety of object-oriented language to start with.

So, let’s jump into the most popular ones with their pros and cons to ease your task!

What Do You Have to Know About Object-Oriented Programming (OOP)?

Most of the widespread programming languages are OOP which means that they rely on classes and objects to make the coding process well-structured and easier compared to non-OOP, or procedural languages.

Within the concept of OOP, anything can be an object — a client, an item, or whatever you need in your task. Let’s say, we need to describe counties. Then, the USA, Australia, and France will be objects.

All these objects will lie under the class of countries.

Here’s what it looks like:

Class of countries
Class of countries

Now with some gasp of the definition, let’s go over the most popular languages to choose from.

Top Object-Oriented Programming Languages to Learn in 2021

There are more than 90 OOP languages out there, but of course, you don’t need to know them all. Most programmers learn 3 to 5 languages within their career and everyone starts with learning one.


Here’s the list of most popular and at the same time well-demanded languages to choose from.


If you ask any programming expert of current times, you will know that java is the language behind many enterprise applications today. Its worldwide recognition is no joke and has been there since 1996. Most programmers agree that Java offers the easiest syntax. No wonder it stands out among other languages. Additionally, the phrase we all know “write once, run anywhere” sets it out as it runs with any device that supports JVM (Java Virtual Machine).


Java’s Pros:

  • It is the easiest for many beginners. Other languages have complex syntax while Java is giving away the easy way to dive into the language and master it with solid practice. As a solid first step, you may take a comprehensive GodeGym Java tutorial and move from the basics to complete real-life tasks.
  • Market demand is also huge and not just for enterprises. Even startups develop their ideas based on this one language.
  • Scalability is another factor to count. Distributed caching solves the challenge of horizontal scalability by allowing a web application to retrieve data from quick local memory rather than a slow serialized data source. Because the program no longer has access to the external bottleneck, it may scale linearly by simply adding more nodes to the cluster.
  • It is compatible with all android devices. Check around and you will see every other person on the phone. So, Java being the compatible language is a huge plus for the companies.
  • The extensive framework gives huge benefits to the developers to explore their options and have full freedom of creating a masterpiece.


Java’s Cons:

  • It will take up a lot of space – sometimes taking up all of your RAM.
  • It lacks the ability to offer frameworks to build a great UI. There are many popular frameworks, but none of them is considered to build a good UI.


Python is recently gaining fame and all for the right reasons. AI is the new normal and Python is the tool for AI developers as it is simple and versatile. Today scientists prefer it over other languages because of the insightful data analysis and deep learning.


Python’s Pros:

  • The major pro is simplicity. This can be counted as another language that makes learning easy.
  • High productivity is high in demand for ongoing economic solutions. The compatible debuggers and easy syntax with the capacity to link with various languages are amazing.
  • Free licensing makes it a developer-friendly language. You also get volunteers providing pre-constructed language solutions on a regular basis.
  • Built-in libraries give you open choice to work with Web, desktop, mobiles, machine learning, etc.


Python’s Cons:

  • Python is known to be slower than various OOP languages.
  • It May not be applicable for Not quite multi-threaded programming.


Kotlin is another open-source language supporting both functional and object-oriented programming. Kotlin also offers quite similar syntaxes just like Java, Scala, and C#.


Pros of Kotlin:

  • It’s concise that enables the ability to write codes with fewer lines. For example, Kotlin provides concise APIs with Pivotal’s well-renowned Spring Framework.
  • Java compatibility gives you more choices for the creation of Android using JVM.
  • Code maintenance is always to the point. A number of important IDEs, like IntelliJ IDEA and Android Studio, are compatible with this language, and it is easy to maintain code.


Kotlin’s Cons:

  • Since the language is still getting popular, you will find it hard to get expert advice.
  • It reduces productivity due to comparatively low compilation speed.


Scala (Scalable Language) as the name suggests is a language that combines object-oriented and functional programming methodologies. Ultimately, allowing for a more perfect programming style and reducing the number of code developers.


Scala’s Pros:

  • Scala’s syntax is quite simple to begin learning.
  • Scalability is pretty much understandable. The term “Scala” is a combination of the words “scalable” and “language.”
  • Works great for data analytics. It became the best for data analytics due to the ease of use with technologies such as Apache Spark and others. This is why several corporations use Scala for their products and services.


Scala’s Cons:

  • Sometimes the quality of hybrid function can get in the way of understanding it.
  • It has a quite small developer community.


You probably remember it by the name of Go. It is a newer open-source programming language. It’s statically typed and comes with its own testing tools and junk collection. Overall it keeps developers away from worrying about memory management.


Golang’s Pros:

  • Easy syntax and also similar to the C-style. If you have a large project, go for the GO.
  • Built-in testing enables you to run end-to-end use cases and ensure the quality just like Dailymotion did for their platform.


Golang’s Cons:

  • There is no way to manual memory management
  • Lacks safety at Runtime.


Ruby is an object-oriented, dynamically typed, open-source programming language. Developers prefer it for the backend along with web development needs.


Ruby’s Pros:

  • Time-effectiveness. Developers often utilize Ruby since they need to build quickly. The Ruby programming language was founded on Twitter.
  • Stability and forecasting. One of the reasons for selecting Ruby to handle its over 50 million client database was Etsy.
  • High concentration on testing. Technology-specific testing frameworks.


Ruby’s Cons:

  • Poor speed, affecting scalability and performance
  • A lack of well-developed documentation
