check for nonnumeric values entered via the java.util.scanner?

[Kat Rollo]

Hi,

Was it the scan.nextLine() instead of scan.next() to discard?

Oh and the \n\n was there because I just wanted some space before it prompts "Enter a number: " again. Really just OC attack. >_<

No, there is a much more serious mistake, I am afraid. Chucking myScanner.next() away is the correct thing to do in those circumstances.
You can easily get two line ends like this:- System.out.printf("%s is brilliant%n%n", "Campbell");

Only you can never get anybody to read it
