## What it is
A program that reformats Java source code to comply with Google Java Style, usable from the command line or via an IntelliJ/JetBrains plugin. It deliberately offers no configurability of the formatting algorithm to enforce a single unified style.

## Use cases
- format java code to google style
- reformat java source files from the command line
- enforce consistent code style across a java project
- format only changed lines in a patch
- integrate google java style formatting into intellij

## When to choose
- your team has adopted Google Java Style and wants automatic enforcement
- you want an opinionated formatter with zero configuration debates
- you need CLI formatting or IDE integration for Java code

## When to avoid
- you need customizable formatting rules or a different style guide
- your project uses a JDK older than the minimum required version and you cannot use the native binaries
- you work primarily in languages other than Java

## Facets
- artifact type: cli-tool
- maturity: active
- function: formatter, cli
- domain: developer-tools, programming-languages
- platform: jvm, cli, cross-platform
- tags: java, code-style, google-java-style, intellij-plugin, code-formatting
