I use int.
Just so you know, it is not only for consistancy. While most people use int, not Integer, there is more to it. If you are going to do uint[ int.Max ], you would waste memory on pointers. And this is crucial for stuff like BioInformatics.
Of course, it is kinda pointless to use Java on BioInformatics. Everyone has tried on Java gave up and switch to C++ due to massive performance issues.
