Difference between JFormatterTextField and JTextField

[Avani Joshi]

Hi,
Can anyone please tell me the differnce between calling a setDocument method using JFormatterTextField and calling setDocument method using JTextField.

- Thanks in advance

A JFormattedTextField has, as the name implies, a format for the text to be filled in. A JTextField can have any text filled in.

Usually you use JTextField. Only use JFormattedTextField if you need the input to have a specific format, e.g. phone numbers, (___) ____

[Brian Cole]

JFormattedTextField differs from JTextField in that it can support

locale-specific display

restrictions on its value

editing non-Strings [via setValue(Object)/getValue()]

incrementing/decrementing from the keyboard

But you ask about specifically about setDocument(), which behaves
about the same.

I'd say that it's rare to call setDocument() on a JFormattedTextField.
Usually one would call setValue() instead, and let the field (and its
formatter) manage the Document for you.
