What is a 'good-practice' method of validating a numeric string? Ive been lazy and am doing a Integer.parseInt() in a try catch but its probably far from the best way... (Have been meaning to check out the java.text.NumberFormat stuff but always had more interes... uh... important things to do first and havent had time yet...)

Check out the static methods of the java.lang.Character class. isDigit() should solve your dilemma.

I mean I can simply convert this String to an Integer, but I doubt this would help, cause a String can get converted to an Integer. (Like A is 65 I think) So how can I be sure that the user typed 65 and not A ? Marcus [EMAIL PROTECTED] schrieb: > > Are you kidding? Dude, everything typed in an HTML form is a string.
