<h3>e996. Creating a Text Field to Display and Edit a Date</h3>
This example uses a <code>JFormattedTextField</code> to allow the display and
editing of a date. By default, when the component loses the focus and
the modified value is a valid date, the modified value is
saved. Otherwise, if the modified value is not a valid date, the
modified value is discarded and the old value is displayed.
<pre> // Support a date in the MEDIUM format in the current locale;
// see <a href="../java.text/FormatDateDef.html" class="eglink"><b>e322</b> Formatting and Parsing a Date Using Default Formats</a>.
// For Locale.ENGLISH, the format would be Feb 8, 2002.
JFormattedTextField tft1 = new JFormattedTextField(new Date());
// Support a date in the SHORT format using the current locale.
// For Locale.ENGLISH, the format would be 2/8/02.
JFormattedTextField tft2 = new JFormattedTextField(DateFormat.getDateInstance(DateFormat.<font color="#0066ff"><i>SHORT</i></font>));
tft2.setValue(new Date());
// Support a date with the custom format: 2002-8-2
JFormattedTextField tft3 = new JFormattedTextField(new SimpleDateFormat(<font color="#0066ff"><i>"yyyy-M-d"</i></font>));
tft3.setValue(new Date());
// See also <a href="../java.text/FormatDate.html" class="eglink"><b>e320</b> Formatting a Date Using a Custom Format</a>
// Retrieve the date from the text field
Date date = (Date)tft3.getValue();
</pre>
The following example demonstrates how to dynamically change the format:
<pre> // Change the format to: 2/8/2002
DateFormatter fmt = (DateFormatter)tft3.getFormatter();
fmt.setFormat(new SimpleDateFormat(<font color="#0066ff"><i>"d/M/yyyy"</i></font>));
// Reformat the display
tft3.setValue(tft3.getValue());
</pre>
