Java scanner issue - input mismatch

Question

How do you separately scan a int and a letter most efficiently in Java? For example scan "6L" and save 6 as an int and register L.

Example code would have helped, as Stack Overflow is generally meant for debugging, it isn't really a programming tutorial forum. However, it's a good question, so here's what I suggest to you for any complicated analysis of text.

If you're already using something retro like a scanner, scan a String containing your textual representation. Once you have the String, use regular expressions.

In your case, that would be something like this:

String sz = scanner.next();

Pattern pattern = Pattern.compile("(\\d+)(\\w+)");  //meaning some number
// of digits, immediately followed by some number of word characters
Matcher matcher = pattern.matcher(sz);

int number = Integer.parseInt(matcher.group(0));
String letters = matcher.group(1);

And there you have it (though note that that particular expression does not understand decimal points, you would have to modify it.)

You can find a complete explanation of regular expressions here, and a handy site for testing them out here. I hope that solves your problem. Good luck!
