Using DefaultFormatterFactory to control JFormattedTextField

   <source lang="java">

import java.text.DateFormat; import java.text.SimpleDateFormat; import javax.swing.JFormattedTextField; import javax.swing.JFrame; import javax.swing.JLabel; import javax.swing.JPanel; import javax.swing.JTextField; import javax.swing.text.DateFormatter; import javax.swing.text.DefaultFormatterFactory; public class DefaultFormatterFactoryDemo {

 public static void main(String args[]) {
   JFrame frame = new JFrame("Mask Input");
   frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
   JLabel label = new JLabel("Date");
   DateFormat displayFormat = new SimpleDateFormat("yyyy--MMMM--dd");
   DateFormatter displayFormatter = new DateFormatter(displayFormat);
   DateFormat editFormat = new SimpleDateFormat("MM/dd/yy");
   DateFormatter editFormatter = new DateFormatter(editFormat);
   DateFormat nullFormat = new SimpleDateFormat(""null"");
   DateFormatter nullFormatter = new DateFormatter(nullFormat);
   DefaultFormatterFactory factory = new DefaultFormatterFactory(displayFormatter,
       displayFormatter, editFormatter, nullFormatter);
   JFormattedTextField input = new JFormattedTextField(factory);
   input.setColumns(30);
   JPanel panel = new JPanel();
   panel.add(label);
   panel.add(input);
   frame.add(panel,"North");
   frame.add(new JTextField(),"Center");
   frame.pack();
   frame.setVisible(true);
 }
