Modern Java Demo

This repository showcases a series of progressive examples demonstrating modern Java development practices with Quarkus.
It focuses on comparisons with legacy frameworks and illustrates how to build AI-infused applications.

Overview

The project is organized into three main modules:

1. 1-hello-quarkus
   Introduces a basic Quarkus application to get started with the framework.
   It covers REST endpoints, Panache, Kafka, and more, serving as a foundation for understanding Quarkus and its capabilities.

2. 2-todo-apps
   Presents a simple Todo application, illustrating RESTful APIs and persistence.
   It shows how to build a full-stack application using Quarkus, including database access with Panache and Hibernate ORM, and integration with a PostgreSQL database.
   It also compares Quarkus with legacy frameworks like Spring Boot and Jakarta EE, highlighting its advantages for modern Java development.

3. 3-ai-infused-applications
   Demonstrates how to integrate AI capabilities into Java applications, leveraging modern libraries and APIs to build intelligent and cognitive systems.

Each module is self-contained and can be run independently.

Prerequisites

• Java 21 or higher
• Apache Maven 3.9 or higher
• Docker or Podman (for modules requiring containerized services via Quarkus Dev Services)
• Hyperfoil (for performance comparison) - download Hyperfoil from: https://hyperfoil.io/ and add the bin directory in your system PATH

Getting Started
