No, it's not the latest and greatest energy drink marketed to developers. RoboGuice is a framework that uses Google's Guice library to make dependency injection a breeze. Dependency injection handles initializing your variables at the right time so that you don't have to. This really cuts down the amount of code you have to write overall, and it makes maintaining your application a breeze in the future. Source code: http://code.google.com/p/roboguice.
