Java Formatter and Beautifier

This code beautifier formats Java source code with proper indentation and spacing. The algorithm analyzes brace structure to determine correct indent levels for classes, methods, conditionals, and loops, producing clean, readable code.

Users can select 2-space or 4-space indentation to match project standards. The formatter normalizes spacing around operators and after keywords while preserving comments and string literals. It handles common Java constructs including class definitions, method declarations, and nested blocks.

Processing uses client-side JavaScript, eliminating the need for Java runtime or build tools. This makes it ideal for quick formatting of code snippets without uploading to external servers.
