Using MaskFormatter - flexible field length?

Hi,

I read "Using MaskFormatter" @ 
http://java.sun.com/docs/books/tutorial/uiswing/components/formattedtextfield.html

I like that the cursor is kept within "valid lengths" so that users 
can't put in Aaaaaaaaaaaaaaaaaaaaaaaaaa in a VARCHAR(10) field.
I know this can be validated afterwards though.

I have 2 questions:

1) I have a ZipCode field but sometimes Zip can be 9 long so I put my 
mask to "#########". Now 9 digits must be filled in. How can this be 
made so 0 to 9 digits is acceptable?

2) For a string field, mask "****" the TextField is padded with right 
spaces (" "). Upon clicking in a field like that the cursor is not in 
the end of the words written (if shorter than length) but rather in 
"open" space. Can this behavior be changed (i.e. no padding)?

Should I use another method for "cursor limiting".

Any and all help is appreciated.
