## What it is
An example Java project demonstrating what Clean Architecture looks like in practice, created to accompany a presentation. It illustrates structuring an application around use cases rather than frameworks or the database.

## Use cases
- learn clean architecture in java
- example of hexagonal architecture project
- how to structure a java app around use cases
- reference for separating business logic from frameworks
- teaching software architecture patterns
- see a testing strategy for layered architecture

## When to choose
- you want a concrete, readable Java codebase to learn Clean Architecture concepts
- you are preparing a talk or training material on architecture
- you want an example of keeping business logic independent of frameworks and the database

## When to avoid
- you need a production-ready framework or starter template
- you need a maintained library with a license for commercial reuse
- you work outside the JVM/Java ecosystem

## Facets
- artifact type: learning-resource
- maturity: maintenance
- function: developer-tools, testing
- domain: developer-tools, tutorials
- platform: jvm
- tags: clean-architecture, java, example-project, software-architecture, hexagonal-architecture, educational, algorithms
