Java is not going anywhere: the banking, insurance, telecom and logistics systems you maintain will get AI components, they will not be rewritten. The ecosystem has lined up, with Spring AI, LangChain4j, official OpenAI and Anthropic SDKs for Java and an official Java SDK for the Model Context Protocol. None of the courses here is written in Java: their examples are mostly Python. They are on this page because what they teach, how a model behaves in production and how you design around it, does not depend on the language.
A Java developer has an advantage that AI prototypes usually lack: the discipline of large systems. Transactions, observability, resilience, security and governance are what decides whether a project gets past the pilot. Add an understanding of language models, RAG and agents, and you are the person who can take AI into the systems that matter.
The risk is treating the model as one more REST service. It is not: the answer is non-deterministic, cost is per token, latency is measured in seconds and quality has to be measured with new metrics. The courses below are chosen to give you that mental model and the operating practices, not to turn you into a Python developer.
Where the model sits in your architecture, how you handle timeouts and retries, how you isolate cost per client, how you log prompts without exposing personal data: decisions you make, not the framework.
Documents, tickets, contracts and relational databases become context for models. Chunking, embeddings, document-level permissions and retrieval evaluation are new requirements for backend teams.
Your services, order lookup, invoicing, stock queries, become tools for agents and assistants, with authentication and least-privilege permissions. The protocol has an official Java SDK.
Coding agents work on large Java codebases too. The difference is made by the context you give them, deterministic hooks and verification wired into CI.
Each of these changes has at least one course in the track below. See the track
When you have gone through all the lessons of a course and have an average of at least 70% on its quizzes, you issue from your account, after confirming the conditions, a Certificate of Completion with a unique number and a public verification link. It is not issued automatically and it comes at no extra cost, with a plan or with single-course access.
A private attestation of course completion. It is NOT a diploma or a state-recognised qualification under Romanian Laws 198/2023, 199/2023 or Government Ordinance 129/2000; employers may take it into account at their own discretion.
In the order in which they matter. If you already have experience with model APIs, skip the foundations. For each course, the reason it matters to someone who works with Java.
Language-independent on purpose: the mental model of LLMs, prompting for code and for systems, and the integration patterns of a production service. The code examples are mostly in Python.
AI and LLM fundamentals, working with APIs, RAG and agents at concept level: the frame you need before any architecture decision.

What already exists, so that you do not start from zero. The courses in the track teach you what to build with it.
These are the skills you practise in the courses of the track; results depend on the time you invest and on your previous experience.
Start the Java trackCode examples, architectures and case studies, and in some courses a capstone project at the end. Not summaries of documentation, but structured material that you go through in order, at your own pace.
You ask in the context of the lesson, by typing or by voice, and get an explanation of the concept you are on. Every lesson has its quiz: about 354 questions per course on average. The professor is an AI system, not a human teacher, included in every plan with a fair-use limit.
Agentic coding, MCP, RAG, agents, evals, LLM security, fine-tuning, AIOps, computer vision and Edge AI are whole courses in the catalog, not closing chapters.
A preview of the first lesson of every course can be read without an account. Then you choose a single course, €99 per month, or IT Pro, €399 per month, with the whole IT catalog. You can stop the renewal anytime from your account; access stays until the end of the period already paid for.
The courses on this page are IT courses. With the IT Pro plan you have the whole IT catalog, the technical learning paths and the AI Professor; if you want only one course, you buy it separately.
When you care about a single topic in the catalog
about €4 per hour of course
Developers, data engineers, architects. Code and production.
€16 per month for each of the 25 courses
The whole catalog, both tracks side by side.
€10 per month for each of the 50 courses

The same skills, seen from each ecosystem. The languages close to Java are highlighted.
No. The code examples are mostly in Python, and the MCP course also has a module in TypeScript. The courses are chosen here for the concepts, architecture and production practices that you then apply with Spring AI, LangChain4j or the official Java SDKs. That is also why this track has two stages instead of three: it lists only the courses whose substance does not depend on the language.
Not in order to change languages. It is worth being able to read Python, so you can follow the examples, the documentation and the evaluation tools, but enterprise Java systems will get their AI components in Java. Your value is in architecture, integration and operations, not in rewriting applications.
Yes, although it is not on this track: the course on fine-tuning open-source LLMs covers open-model licenses, quantization and self-hosting with Ollama, vLLM and TGI, and it is part of the same IT Pro plan. The AI security course covers data protection, PII and leakage.
All the courses recommended here are IT courses and open with the IT Pro plan, which includes every IT course in the catalog. It is billed monthly, and you can stop the renewal anytime from your account. There is also individual, monthly access to a single course. Every course has a free preview of its first lesson, readable without an account.
9 courses, ~227 hours, opened with IT Pro: €399 per month, VAT included, with access to all 25 IT courses. The AI Professor is included in every plan.
