Formatting and Parsing a Date Using Default Formats</h3>
Every locale has four default formats for formatting and parsing
dates. They are called <code>SHORT</code>, <code>MEDIUM</code>, <code>LONG</code>, and
<code>FULL</code>. The <code>SHORT</code> format consists entirely of numbers while
the <code>FULL</code> format contains most of the date components. There is
also a default format called <code>DEFAULT</code> and is the same as
<code>MEDIUM</code>.
<P> Note: This example formats dates using the default locale
(which, in the author's case, is <code>Locale.ENGLISH</code>). If the example
is run in a different locale, the text (e.g., month names) will not be
the same.
<pre>
// Format
Date date = new Date();
String s = DateFormat.getDateInstance(DateFormat.<font color="#0066ff"><i>SHORT</i></font>).format(date);
// 2/16/02
s = DateFormat.getDateInstance(DateFormat.<font color="#0066ff"><i>MEDIUM</i></font>).format(date);
// Feb 16, 2002
s = DateFormat.getDateInstance(DateFormat.<font color="#0066ff"><i>LONG</i></font>).format(date);
// February 16, 2002
s = DateFormat.getDateInstance(DateFormat.<font color="#0066ff"><i>FULL</i></font>).format(date);
// Saturday, February 16, 2002
// This is same as MEDIUM
s = DateFormat.getDateInstance().format(date);
// Feb 16, 2002
// This is same as MEDIUM
s = DateFormat.getDateInstance(DateFormat.<font color="#0066ff"><i>DEFAULT</i></font>).format(date);
// Feb 16, 2002
// Parse
try {
date = DateFormat.getDateInstance(DateFormat.<font color="#0066ff"><i>DEFAULT</i></font>).parse(<font color="#0066ff"><i>"Feb 16, 2002"</i></font>);
} catch (ParseException e) {
