Java Code Formatter & Beautifier

Java Code Formatter & Beautifier

Format and beautify your Java code instantly with industry-standard style presets. Paste messy or inconsistently formatted Java code and get clean, properly structured output that matches Google Java Style or Oracle Code Conventions — with full control over indentation, brace placement, and import sorting.

Anwendung

Paste your Java code into the input area. Select a style preset to auto-configure formatting options, or manually adjust indent width, brace style, and import sorting to match your project conventions. The formatted code updates instantly in the output panel — copy it with one click.

Merkmale

• Style Presets – One-click formatting with Google Java Style (2-space indent, 100-char lines) and Oracle Code Conventions (4-space indent, 80-char lines).
• Import-Sortierung – Automatically groups and sorts import statements: java.* first, then javax.*, then third-party packages, then static imports.
• Annotation Handling – Keeps annotations on separate lines before declarations, properly formatted and indented.
• Brace Styles – Choose between end-of-line (K&R) or next-line (Allman) brace placement for classes, methods, and control structures.
• Konfigurierbare Einrückung – Set indent width (2, 4, or 8) and choose between spaces or tabs.
• Leerzeilen-Normalisierung – Enforces consistent spacing between methods, fields, and class sections.
• Echtzeit-Formatierung – Output updates instantly as you type or change any formatting option.

Wann Sie dieses Tool verwenden sollten

Use this tool when cleaning up Java code for code reviews, standardizing formatting before committing to a shared repository, or converting between Google and Oracle style conventions. It’s especially useful for reformatting code snippets for documentation, tutorials, or Stack Overflow answers where consistent formatting matters.
