Gunlighter calculatore

So who wants to go ahead and download/trust a calculator from someone who doesn't know the name of the class and can't spell "calculator"? I can't wait until he makes it.

You're gonna get a NullPointerException from an excel spreadsheet.

Or Java, for that matter.

(In this case, obviously)

I know Java better than I know C# (I think), which is what I made my calculator in, and I find it much less user-friendly in the end (both the program, and the programming).
