Why do I get a repeating modifier error when compiling?

I copied this code from this site and am trying to adapt it to our environment. Sorry, I cannot get $%! @ # * ($ Thing for compilation. I keep getting an error with the main method: error: re-modifier.

public static void main(String... aArgs) throws FileNotFoundException is a string marked for error.

I do not see any duplicate modifiers here. All my braces and parens seem to be in the right places, and I'm completely at a dead end.
