eBook: Understanding LangChain4j

Artificial Intelligence (AI) and Large Language Models (LLMs) are rapidly transforming the way we develop and interact with software applications. Integrating these advanced technologies into Java applications, however, can be a daunting task due to their complexity and the sheer volume of concepts involved. That’s where LangChain4j comes into play. In this fascicle, you will learn LangChain4j, the Java library that simplifies the integration of AI and LLMs into your applications. You will explore the fundamentals of AI, learn the history and evolution of AI models, and understand the core concepts of LangChain4j. From accessing and invoking large language models to manipulating embeddings in vector databases, you will gain hands-on experience through practical examples and code snippets. Additionally, you will discover advanced topics such as Retrieval-Augmented Generation (RAG), debugging, testing, and integrating LangChain4j with other technologies.

Hi, I’m Antonio Goncalves


I am a senior developer living in Paris. I evolved in the Java EE landscape for a while and then moved on to Spring, Micronaut and Quarkus. From distributed systems to microservices and the cloud, today I help my customers to develop the architecture that suits them the best.

Aside from freelancing for my customers, I write books (Java EE and Quarkus), I create online courses, I talk at international conferences (Devoxx, JavaOne, GeeCon…), I write technical papers, articles and I co-present on the Technical French pod cast called Les Cast Codeurs. I've co-created the Paris JUG, Voxxed Microservices and Devoxx France. For all my work for the community I have been made Java Champion.
