LangChain4J is a Java-based library inspired by the popular Python library LangChain. It is a framework for Generative AI applications, allowing developers to connect various building blocks that can easily create powerful AI applications.

This talk will present the main LangChain4J building blocks that developers can use to integrate different parts like large language models (LLMs), embedding stores, document loaders, text splitters, output parsers, and more.

Several code samples in Java will be presented, along with an Oracle Database to support the examples.
