Frequently asked questions

Which brace style should Java use?

K&R (opening brace on the same line) is the convention in Oracle and Google Java style guides.

Is the Java Formatter free?

Yes. It is free with no sign-up, and it runs entirely in your browser, so your input is never uploaded or stored.

Will formatting change how my code behaves?

Formatting only changes whitespace and layout. Minifying removes comments and whitespace and may shorten names, so keep the original source in version control.
