amount of digits entered(without a tokenizer)....

[Brandi Love]

Without using a tokenizer, how can I determine the amount of digits in an integer entered by a user? (Say the user enters 123,345. I need to somehow within the program determine that there are 6 digits)

Convert to a string and do a length.

[Brandi Love]

how do you do that?

With out looking in any books I would guess something like this:

 
int i = 10234 ;
String numString = new String( int) ;
int size = numString.size() ;

I am not saying that this is the best way, only one way.

This is probably sloppy, but I concatenate an empty string with a number to make it a string now and then:
int i = 12312312;
int digits = (""+i).length();

That is actually the easiest way. You could also use the static toString(int i) method of Integer:
int digits = Integer.toString(i).length();

Thanks guys I ended up just doing a string length.
