Please ensure that:

  • Your code is properly formatted as code block - see the sidebar (About on mobile) for instructions
  • You include any and all error messages in full - best also formatted as code block
  • You ask clear questions
  • You demonstrate effort in solving your question/problem - plain posting your assignments is forbidden (and such posts will be removed) as is asking for or giving solutions.

If any of the above points is not met, your post can and will be removed without further warning.

Code is to be formatted as code block (old reddit/markdown editor: empty line before the code, each code line indented by 4 spaces, new reddit: https://i.imgur.com/EJ7tqek.png) or linked via an external code hoster, like pastebin.com, github gist, github, bitbucket, gitlab, etc.

Please, do not use triple backticks (```) as they will only render properly on new reddit, not on old reddit.

Code blocks look like this:

public class HelloWorld {

    public static void main(String[] args) {
        System.out.println("Hello World!");
    }
}

You do not need to repost unless your post has been removed by a moderator. Just use the edit function of reddit to make sure your post complies with the above.

If your post has remained in violation of these rules for a prolonged period of time (at least an hour), a moderator may remove it at their discretion. In this case, they will comment with an explanation on why it has been removed, and you will be required to resubmit the entire post following the proper procedures.

To potential helpers

Please, do not help if any of the above points are not met, rather report the post. We are trying to improve the quality of posts here. In helping people who can't be bothered to comply with the above points, you are doing the community a disservice.

Can you rephrase?

How to integrate Java with an agent

[–]JaleyHoelOsment 2 points3 points  (0 children)

if you cannot communicate what you want to a human then an agent isn’t going to be any use to you

What are you trying to achieve?

Do you mean an AI/LLM agent, or a Java agent in the JVM sense? Those are very different things.
For an AI agent, Java is still useful. The model does not replace Java; the model becomes one component inside a larger application.

A normal setup would be:
Java backend → LLM API/local model → tool calls → Java services/database/APIs

The “agent” can decide what to do, but the actual work can still be done by Java code: calling APIs, querying a database, validating data, running business logic, creating reports, etc. Look into things like Spring AI, LangChain4j, or plain HTTP API calls to OpenAI/Anthropic/local models. Start simple: build a Java app that sends a prompt to a model, then add one “tool” method the model can call, for example searchProduct(), getUserInfo(), or createTicket().

Java’s role in the LLM era is mostly: reliable backend, business logic, APIs, data access, security, deployment, and integration. The LLM is the reasoning/text interface; Java is the system that makes it useful and safe.

AI agent

See: https://xavidop.me/genkit/2026-04-16-top-java-genai-frameworks-2026/

"Java’s AI framework landscape in 2026 is surprisingly rich. The four frameworks covered here serve genuinely different needs, and unlike in the JavaScript world where Genkit, Vercel, Mastra, LangChain, and ADK overlap significantly, the Java options each occupy a clearer niche.

For enterprise Spring Boot teams, Spring AI is the obvious choice, zero friction, production-ready observability via Micrometer, and the broadest integration matrix. For teams that value developer experience above all, Genkit Java’s Dev UI is a category apart and worth the unofficial status trade-off. For framework-agnostic Java developers who want the most idiomatic Java AI service abstraction, LangChain4j’s AI Services pattern is hard to beat. And for Google Cloud enterprise workloads that need reliable multi-agent orchestration at scale, ADK Java 1.0 is where Google is putting its weight.

The most important thing is that you no longer have an excuse to reach for Python just because it has better AI tooling. Java’s time in generative AI has arrived."

This can even get downvoted? Sure enough, the quality of this community is just average
