Well, the java language gives you all you need for such thing.
You can use somthing like the following
String _is_it_int = "abc";
try {
Integer _int = Integer.parseInt(_is_it_int) ;
} catch (NumberFormatException ex) {
// This was not an int:
}
for parsing the values. Then you can make a check for the size.
If you do this often put it in your own input validation class.
But probably this is like reinventing the wheel.
frameworks like Turbine from Apache should provide the same
functionality.
