Time and time again I see Java beginners not taking the time to clean up their code before posting it so I whipped up this very rudimentary code beautifier "Indentify". My beautifier of choice is the Eclipse IDE but most beginners haven't gotten to the point of using IDEs yet. Maybe, just maybe, this will help someone out and make our collective lives easier.
Actually, I used Jalopy (http://jalopy.sourceforge.net), which actually blows away the built-in IDE beautifiers when it come to customization. It ran stand-alone or as a plug-in to most popular IDEs. Could even be set up to do batch processing to enforce formatting on entire projects.
Originally, and in the SourceForge version, it was free software. It seems to have been converted to commercial software now ($40/seat). And it may be orphaned entirely now, alas - last update seems to have been in 2010.
An IDE is no substitute for an Intelligent Developer.
