Thanks to Prof. Michel Charpentier for the insightful session last night on #functionalprogramming in #Java, and to Eric Deandrea for the lightning talk on #Java and #AI with #LangChain4j.

We recorded last night's sessions. The recordings are available at https://www.youtube.com/playlist?list=PL-ZeawwvkKOBbtTJv5ZK6P7Nrl-30ENNQ

#Java + #AI sounds great — until you hit streaming, memory & RAG. @nicolas_frankel shows how #LangChain4j cuts through the complexity: local #LLMs, clean #APIs, no lock-in.

Expanding ADK Java LLM coverage with LangChain4j https://glaforge.dev/posts/2025/06/05/expanding-adk-java-llm-coverage-with-langchain4j/
#Java #ADK #langchain4j

An interesting perspective: to extend #ADK for #Java with
#langchain4j so your Java #Agents can use any model supported by #LangChain4j or #ollama (including local models like #gemma, #qwen, #phi, etc.)
