public class DateFormatter extends InternationalFormatter
DateFormatter is an InternationalFormatter that does its formatting by way of an instance of java.text.DateFormat.

Warning: Serialized objects of this class will not be compatible with future Swing releases. The current serialization support is appropriate for short term storage or RMI between applications running the same version of Swing. As of 1.4, support for long term storage of all JavaBeans has been added to the java.beans package. Please see XMLEncoder.
