Hi folks, I want to write grammar rules for a form entry application.
On the form/frame I have some fields:
Customer name, telephone number
I check the validity of the textfileds before data saved.
What can be the grammar for a telephone number and name considering that users shud not enter spaces, wild chars, alphanumeric chars, etc...
Thanks.

See, alphanumeric means alphabets and numbers.
So a user can enter 987r65436u by mistake.

I think for this purpose you will want to use regular expressions.
Check out the API for the java.util.regex package.

There are no stupid questions, only those too stupid to ask for help.
