Is Java Still Worth Teaching to New Computer Science Students

Java has been a pillar of computer science education for decades.
Each quarter, I revisit a familiar question: Is it still worth teaching Java to new computer science students? As a professor deeply invested in preparing the next generation of developers, I wrestle with this question not out of nostalgia, but out of responsibility. In a world rapidly adopting Python, JavaScript, and newer paradigms like functional programming and AI-focused languages, Java can feel like yesterday’s news. But the truth is more nuanced.
Java has been a pillar of computer science education for decades. It teaches critical concepts like object-oriented programming, static typing, and memory management in a way that is explicit and structured. For new students, these are not just language features—they are foundational ideas. Mastery of Java often translates to easier transitions into C++, C#, or even newer JVM languages like Kotlin.
Still, I understand the critique. Java is verbose. Its syntax, while precise, can be intimidating. In contrast, Python’s clean and forgiving style feels more accessible and modern. Some argue that Python is better suited for engaging beginners, especially in data science, AI, and scripting tasks. And they're not wrong—Python lowers the barrier to entry. But the ease of entry shouldn’t replace the depth of understanding.
Where Java continues to prove its relevance is in industry demand. From backend web services to Android apps and large-scale enterprise systems, Java is still everywhere. According to recent job boards and developer surveys, Java consistently ranks among the top languages in demand. Companies still build core infrastructure in Java, and learning it opens real employment opportunities.
Teaching Java also has long-term benefits. Students who learn Java early often develop strong debugging habits, a clearer understanding of data types, and a more rigorous approach to program design. These skills don’t go out of style.
So is Java still relevant? Yes. Should we keep teaching it? Yes—but with intention. I believe we must teach Java as a bridge to deeper learning, not as an end in itself. We should pair it with modern practices, emphasize real-world use cases, and remain open to evolving our curriculum.
The goal isn’t to cling to Java out of habit. It’s to equip students with conceptual depth and career-ready skills—and right now, Java still delivers on both.
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.
