Java - Custom JFormattedTextField - Phone Number

What am I missing in this custom class? When placed on the container, the format is visible. When I start entering the phone number, the format is destroyed (erased).
package myLibrary;

import java.text.ParseException;
import javax.swing.JFormattedTextField;
import javax.swing.text.MaskFormatter;

public class CustomPhoneNumber extends JFormattedTextField {  
    public CustomPhoneNumber() throws ParseException {     
        MaskFormatter formatter = new MaskFormatter("(###) ###-####");

Try this:
JFormattedTextField telephoneNumberField = new JFormattedTextField();
MaskFormatter formatter = new MaskFormatter("(###) ###-####");
telephoneNumberField.setFormatterFactory(new DefaultFormatterFactory(formatter));

Is there a way to make getText() only returns what the user enters. Currently if the users enters 909 999 9999, the getText() returns (909) 999-9999 (with the format).

zzynxSr. Software engineerCommented:
It's not that difficult to strip off what you don't need:

String formattedTelephoneNumber = "(909) 999-9999";  // = yourField.getText();
String telephoneNumber = formattedTelephoneNumber.replaceAll("[-() ]", "");

You re right. Thanks.
I was thinking that there is an attribute or method that will make it return the user input (same logic as it works for the password field).
Thanks for your prompt reply

I think you could also call getValue() instead of getText(). Just try it.
