## Health v2 (maintenance only)
Score: 23/100 (v2, computed 2026-09-03T02:20:16.233290+00:00)
- activity 0, release rhythm 8, longevity 100
- inputs: {"age_days": 3036, "days_push": 1357, "days_rel": null, "gap_med": null, "n_releases_24m": 0}
- flags: none
- formula: round(0.45*activity + 0.35*rhythm + 0.20*longevity); archived -> min(score, 10)

## What it is
A Java-based educational repository explaining classic design patterns with wiki documentation and runnable code examples, including combined real-world usage patterns and design patterns found in Spring source code. It serves as a learning resource rather than a usable library.

## Use cases
- learn design patterns in java
- see real-world design pattern examples
- understand design patterns used in spring framework
- study singleton factory strategy pattern implementations
- find combined pattern usage like facade with chain of responsibility
- prepare for java design pattern interviews

## When to choose
- you are learning or teaching classic GoF design patterns in Java
- you want practical combined-pattern examples from real projects
- you want to see how Spring applies design patterns internally

## When to avoid
- you need a production-ready pattern library to import as a dependency
- you work in a language other than Java
- you need comprehensive coverage of all 23 GoF patterns with formal treatment

## Facets
- artifact type: learning-resource
- maturity: maintenance
- function: developer-tools, documentation
- domain: tutorials, programming-languages, developer-tools
- platform: jvm
- tags: design-patterns, java, spring, educational, code-examples
