Why Aspiring Developers Still Need to Learn Object-Oriented Programming

Object-oriented programming, at its core, is about modeling software systems around “objects” that represent real-world entities
In today’s fast-moving world of software development, it might seem tempting to skip over traditional programming paradigms like object-oriented programming (OOP) and head straight into newer trends like functional programming, data-driven frameworks, or AI tooling. However, OOP continues to be a critical skill that aspiring software developers should master.
Object-oriented programming, at its core, is about modeling software systems around “objects” that represent real-world entities. This approach, which emphasizes encapsulation, abstraction, inheritance, and polymorphism, has been the foundation of most enterprise applications for decades. Whether you are working in Java, C++, C#, or Python, OOP principles show up everywhere. Even if you never create your own elaborate class hierarchies, understanding how objects interact is key to working with frameworks, libraries, and APIs that dominate modern development.
One of the main reasons OOP remains important is that it teaches developers how to think about software design. It enforces structure and modularity, making systems easier to maintain and scale. For instance, when designing a large application like an e-commerce platform, OOP concepts help developers break down the system into manageable components: products, users, orders, and payment modules. Each of these components can evolve independently while still interacting through well-defined interfaces.
OOP also supports the collaborative nature of modern software development. Teams can work on different parts of the codebase with minimal overlap, which is essential for building complex systems across industries such as finance, healthcare, and education.
Even experts in programming education recognize its enduring relevance. In his book Code Complete, Steve McConnell emphasizes that, Good object-oriented design makes code more understandable, more maintainable, and less error prone. This insight highlights why OOP continues to be taught in nearly every computer science curriculum — it fosters long-term skills that apply regardless of language or framework.
Of course, OOP is not the only paradigm developers need to know. Functional programming, declarative approaches, and event-driven systems are all valuable tools. But a strong grounding in OOP provides a solid mental model that makes it easier to pick up these other paradigms later.
For aspiring developers, the message is clear: learn OOP, master its principles, and then branch out. OOP may not dominate every cutting-edge domain, but it is still a cornerstone of professional software development — and will continue to be for years to come.
A mentor gives you advice. A sponsor creates opportunities.
Representation alone will not solve the persistent racial disparities in computing.
The truth is that most software applications exist to manage information.
Artificial intelligence has become the newest member of nearly every software development team.
The true promise of computing is not found in the machines we build, but in the human potential we unlock when knowledge becomes accessible to everyone.
One of the reasons I value the MCT program so highly is that it represents more than technical knowledge.
Software engineering is not simply coding.
Companies often promote the idea that technical skill alone determines success.
Hackathons also strengthen teamwork and communication skills.
Stepping onto the campus of Morehouse College this past weekend for Admitted Students Day was more than a visit—it was a moment of reflection. As I watched young Black men walk with purpose across the yard, I found myself asking a simple but profound question: What would it have been like for me to study computer science here? My journey into computing was shaped in environments where I was often the only Black man in the room. That reality brings with it an unspoken weight—the need to prove you belong, the awareness of being watched, and sometimes, the quiet isolation that comes with underrepresentation. Standing at Morehouse, I realized that this burden is not a given. It is a condition of the environment. At Morehouse, the environment is different by design. Here, Black men are not anomalies—they are the standard. I imagined what it would feel like to learn algorithms, data structures, and software development in a space where my identity was not questioned but affirmed. Where excellence is expected, not in spite of who you are, but because of it. As a computer science professor, I understand the academic rigor required to succeed in this field. There is no shortcut through recursion, no bypass around debugging, no substitute for disciplined problem-solving. But what struck me during my visit is how much context matters. When students are free from the psychological burden of proving they belong, they can redirect that energy toward mastering the material. They can collaborate more openly, ask questions more freely, and take intellectual risks without fear. I also thought about legacy. At Morehouse, students walk the same grounds as Martin Luther King Jr.. That kind of history does something to a person. It raises the bar—not just academically, but personally. It invites students to see their education not just as a pathway to a career, but as preparation for impact. Leaving campus, I felt inspired—but also reflective. I cannot rewrite my journey, but I can appreciate what spaces like Morehouse offer the next generation. For a Black male pursuing computer science, it is more than a degree. It is an opportunity to develop skill, confidence, and identity in alignment. And that combination is powerful.
