Frequently Asked Questions
How does the Java formatter work?
It parses your code and applies consistent indentation based on curly braces. The formatter respects Java syntax: each opening brace increases indent, each closing brace decreases it. It also handles semicolons, comments, and string literals.
Does it work like IntelliJ or Eclipse formatter?
This is a lightweight online formatter - it fixes indentation and line breaks. For advanced formatting (import organization, line wrapping, annotation alignment), use your IDE. Use it when you need a quick format without opening your IDE.
Is my code sent to a server?
No. All formatting happens in your browser using JavaScript. Your code never leaves your computer.
Is this free?
Completely free. No sign-up, no limits, no watermarks.
Frequently Asked Questions
What is a formatter in Java?
A Java formatter rewrites messy source code with consistent indentation, line breaks, and spacing so it is easier to read and review.
Is there prettier for Java?
Prettier does not support Java natively. The closest alternatives are google-java-format, Palantir Java Format, and our browser-based tool which needs no install.
How to format a Java file?
Paste your Java code into the input box and click Format. The tool applies smart indentation to methods, blocks, and control flow, then shows the result ready to copy.
What is a code beautifier?
A code beautifier takes unformatted source code and applies consistent spacing, indentation, and line breaks so it follows the standard Java code conventions.
How to beautify Java code in VS Code?
VS Code can format Java with the Language Support for Java extension. Our online tool gives you the same result without installing anything.
Can I use prettier for Java?
Not directly. Prettier does not have a Java parser. Use google-java-format, Eclipse formatter, or our online tool instead.
