How To Use FormattedFields For Inserting Dates

I know the below code is supposed to format the FormattedTextField but it doesn't seem to do anything to the form (shown in the picture below). I was wanting, when the form loaded: the text field to look something like this

00/00/2014 - 00:00 am

Where the user is able to

- enter datelike information around the symbol separators ( / or : )

- But where the user could not remove these symbol separators

Code:

package datefield;
import javax.swing.JFormattedTextField;
import javax.swing.text.DateFormatter;
public class NewJFrame extends javax.swing.JFrame {
public NewJFrame() {
initComponents();
