Better way than this one?

Someone insert a numer like e.g 123
the output is 3 (number of digits)
Is there any easy way to do that instead of this :
System.out.print ( "insert number: ");
int number = Integer.parseInt(br.readLine().trim());
int count = 0;
int digit= number%10;
if(number >= 0) count++;
I know there's a better way to do this , like with a for- loop or something.
I'm getting a "blank" , can't remember
Thanks a lot.
