- set up a Gradle-based Java learning environment

## When to choose
- you are reading or teaching from the On Java 8 book and want its runnable code
- you want tested, book-accurate Java 8 examples
- you are a beginner wanting a ready-made Java project to experiment in

## When to avoid
- you need a production Java library or framework
- you want examples for Java versions beyond 8-17 features covered in the book
- you use JDK 16+ with Gradle, which is known to break this build

## Facets
- artifact type: learning-resource
- maturity: maintenance
- function: testing, developer-tools
- domain: education, programming-languages, tutorials
- platform: jvm, cross-platform, cli
