Thread: Help With Validation

So I'm trying to use two validations in my program:
5 integers for the first Validation and
the second is 32 characters only including : and |.

The first validation is for a Zip Code and the second is for a Bar Code.

I'm just clueless on how to perform these validations.

My program is set us so you go and it asks enter Z to enter a Zip Code or B to enter a Bar code. From here I have 2 if statements ( if (choice.equals("Z") then perform the Zip Code Part of the Program and if (choice.equals("B") to go to the Bar Code part of the program.

See How to use regular expressions. For example, you could use "[0-9]{5}" to validate the zip code (using String.matches)

I suppose you mean "^[0-9]{5}$"

No I do not. The ^ is not necessary for something like String.matches in the above context (although it doesn't muck anything up either )
