What is LangChain4j and how does it work with Quarkus?

LangChain4j is Java's answer to LangChain — LLM orchestration with agents, tools, RAG. Quarkus extensions add native compile, Dev UI, OTel metrics. Setup in minutes.

Why use Java instead of Python for agentic AI?

Java offers type safety, low-latency GraalVM starts, enterprise integrations Python lacks at scale. Perfect for 24/7 production, not prototypes.

How to build an agentic AI app in Java 2026?

Quarkus CLI, add langchain4j deps, define @Tool methods, wire AiServices. Add MCP for tools, OTel for traces — deploy to K8s.
