## Description

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 easily to 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.

This talk introduces LangChain4J, including its main components and the typical AI-related use cases it supports. The talk will cover several use cases from a business-related standpoint, like building super-intelligent chatbots that use NLP, text summarization, text generation, and question-answering.
Sample code will be presented, along with several live demos.
