So guys, I have a window where I need to go through a validation of null fields of several JTextField and a JFormattedTextField, where the latter has a mask for phone numbers "(##)####-####". The fact is that even though I don’t type anything in this field, it takes the characters from the mask : ()- and understands that the field is not null. I wonder if there’s some method that ignores characters from a mask, or I’ll have to do all that work with substring ? It is worth making clear that I just want to ignore at the time of validation, and not remove these characters, because then I will have to introduce them to the user !
As a matter of fact :
try {
mskTel = new MaskFormatter("(##)####-####");
} catch (ParseException e) {
e.printStackTrace();
}
txtTel = new JFormattedTextField(mskTel);
How the validation is done :
form.txtTel.getText() == null || form.txtTel.getText().trim().isEmpty()
How are you picking up the values of this field? Add a [mcve] so we can analyze the problem.

A "nut" solution would be to check the size of the returned string, its field should have 13 characters, so
form.txtTel.getText() = form.txtTel.getText().trim().length == 13 ? form.txtTel.getText().trim() : null.– user28595
when I apply this solution gives compilation error : "The left-hand side of an assignment must be a variable". So if I try to assign the
form.txtTel.getText()is a String, it accuses another error, and suggests that I add a()after the.length, and from there, the validation no longer works ...– Daniel Santos
It was bad, my mistake. The correct thing is to assign a string variable:
String text = form.txtTel.getText().trim().length == 13 ? form.txtTel.getText().trim() : null– user28595
But this command I put before validation, or replace the corresponding chunk ?

Where do you do this validation? Num if?

Exactly ! See code excerpt : http://pastebin.com/krFV37Vc

Simply replace the validation of Empty: http://pastebin.com/H04xkm9Z
