## What it is
A Visual Studio Code extension providing Java language support via the Eclipse JDT Language Server. It offers code completion, navigation, refactoring, debugging, and Maven/Gradle project integration for Java 1.8 through Java 26.

## Use cases
- write and edit Java code in VS Code with IntelliSense
- get code completion and error reporting for Java files
- import and work with Maven or Gradle projects in VS Code
- refactor and organize imports in Java code
- debug Java applications from the editor
- navigate Java code with type hierarchy and call hierarchy

## When to choose
- you develop Java in Visual Studio Code and want full IDE-like features
- your projects use Maven or Gradle and need integrated build support
- you want a free, actively maintained Java language server extension

## When to avoid
- you use IntelliJ IDEA or Eclipse IDE, which have deeper native Java tooling
- you need support for Java versions older than 1.8
- you work in an editor other than VS Code

## Facets
- artifact type: plugin
- maturity: active
- function: editor, developer-tools, documentation
- domain: developer-tools, text-editors, programming-languages
- platform: editor-plugin, cross-platform, windows
- tags: java, language-server, vscode-extension, code-completion, maven, gradle, lsp, linux, macos
