About This Tool

The tool formats Java source code to a consistent style, aimed at developers, reviewers, and educators who need reproducible formatting outcomes. It accepts a Java source snippet and outputs a reformatted version that adheres to a selected style profile. Conceptually, the formatter parses tokens and structural blocks, then applies indentation, line wrapping, and import ordering according to the chosen profile. It supports profiles such as Google, Oracle, or JetBrains, with options to adjust indentation width and maximum line length. The result is a clean, uniform codebase where diffs focus on semantics rather than stylistic variance. Use cases include modernizing legacy code, standardizing onboarding examples, and streamlining code reviews with predictable formatting outcomes. Unique value lies in profile-based rules, language-aware handling of Java constructs, and offline operation, which enables consistent results without external services. Core features include configurable indent_size, max_line_length, optional sort_imports, and final newline control, along with the ability to preserve blank lines and certain whitespace decisions. This tool differentiates itself from generic formatters by exposing explicit style profiles and a Java-centric rule set suitable for teams following Google, Oracle, or JetBrains conventions. It does not analyze semantics or compile code; it focuses solely on formatting and whitespace normalization. Typical use includes formatting a developer’s snippet before committing changes, preparing teaching examples, or enforcing a team-wide formatting standard across multiple repositories.

How to Use

  1. Provide a Java source code input and select the language as Java.
  2. Choose formatting options such as indent_size, max_line_length, and an optional style_profile (Google, Oracle, or JetBrains).
  3. Enable or disable import sorting and final newline as needed.
  4. Run the formatter to produce formatted_code in the output section.
  5. Review the formatted result and export or copy as required.

Frequently Asked Questions

Find Quick Answers

What languages does this formatter support?
The tool is Java-specific and formats Java source code. Other languages are not processed unless extended with a language-specific formatter.
Can imports be reordered automatically?
Yes. If sort_imports is enabled, the tool reorders imports according to the selected style profile, improving readability in large files.
Will formatting fix syntax errors?
Formatting focuses on whitespace and structure; it does not validate compilation. If syntax errors exist, formatting may not resolve them, though indentation and line-wrapping will still be applied.
Can I export or copy the formatted code?
Yes. The formatter provides the formatted_code output which can be copied, saved, or exported for review or integration into workflows.
