## What it is
A community-maintained summary of Joshua Bloch's book Effective Java (2nd Edition), organized chapter by chapter with code examples. It serves as a quick reference and study aid for Java best practices, not a replacement for the book itself.

## Use cases
- quickly look up Java best practices while coding
- review Effective Java concepts before an interview
- learn object creation, equals/hashCode, and class design guidelines
- find concise explanations of Java idioms like builders and static factory methods
- use as a study companion while reading Effective Java

## When to choose
- you want a free, searchable summary of Effective Java's items
- you need a quick refresher on Java design best practices
- you are studying Java and want structured notes alongside the book

## When to avoid
- you expect a runnable library or tool - this is prose documentation
- you need the 3rd edition content covering newer Java features
- you want an authoritative substitute for reading the actual book

- maturity: maintenance
- function: documentation, developer-tools
- domain: programming-languages, tutorials, developer-tools, education
