/**
* {@code DateFormat} is an abstract class for date/time formatting subclasses which
* formats and parses dates or time in a language-independent manner.
* The date/time formatting subclass, such as {@link SimpleDateFormat}, allows for
* formatting (i.e., date -> text), parsing (text -> date), and
* normalization. The date is represented as a <code>Date</code> object or
* as the milliseconds since January 1, 1970, 00:00:00 GMT.
*
* <p>{@code DateFormat} provides many class methods for obtaining default date/time
* formatters based on the default or a given locale and a number of formatting
* styles. The formatting styles include {@link #FULL}, {@link #LONG}, {@link #MEDIUM}, and {@link #SHORT}. More
* detail and examples of using these styles are provided in the method
* descriptions.
*
* <p>{@code DateFormat} helps you to format and parse dates for any locale.
* Your code can be completely independent of the locale conventions for
* months, days of the week, or even the calendar format: lunar vs. solar.
*
* <p>To format a date for the current Locale, use one of the
* static factory methods:
* <pre>
* myString = DateFormat.getDateInstance().format(myDate);
* </pre>
* <p>If you are formatting multiple dates, it is
* more efficient to get the format and use it multiple times so that
* the system doesn't have to fetch the information about the local
* language and country conventions multiple times.
* <pre>
* DateFormat df = DateFormat.getDateInstance();
* for (int i = 0; i < myDate.length; ++i) {
* output.println(df.format(myDate[i]) + "; ");
* }
* </pre>
* <p>To format a date for a different Locale, specify it in the
* call to {@link #getDateInstance(int, Locale) getDateInstance()}.
* <pre>
* DateFormat df = DateFormat.getDateInstance(DateFormat.LONG, Locale.FRANCE);
* </pre>
* <p>You can use a DateFormat to parse also.
* <pre>
* myDate = df.parse(myString);
* </pre>
* <p>Use {@code getDateInstance} to get the normal date format for that country.
* There are other static factory methods available.
* Use {@code getTimeInstance} to get the time format for that country.
* Use {@code getDateTimeInstance} to get a date and time format. You can pass in
* different options to these factory methods to control the length of the
* result; from {@link #SHORT} to {@link #MEDIUM} to {@link #LONG} to {@link #FULL}. The exact result depends
* on the locale, but generally:
* <ul><li>{@link #SHORT} is completely numeric, such as {@code 12.13.52} or {@code 3:30pm}
* <li>{@link #MEDIUM} is longer, such as {@code Jan 12, 1952}
* <li>{@link #LONG} is longer, such as {@code January 12, 1952} or {@code 3:30:32pm}
* <li>{@link #FULL} is pretty completely specified, such as
* {@code Tuesday, April 12, 1952 AD or 3:30:42pm PST}.
* </ul>
*
* <p>You can also set the time zone on the format if you wish.
* If you want even more control over the format or parsing,
* (or want to give your users more control),
* you can try casting the {@code DateFormat} you get from the factory methods
* to a {@link SimpleDateFormat}. This will work for the majority
* of countries; just remember to put it in a {@code try} block in case you
* encounter an unusual one.
*
* <p>You can also use forms of the parse and format methods with
* {@link ParsePosition} and {@link FieldPosition} to
* allow you to
* <ul><li>progressively parse through pieces of a string.
* <li>align any particular field, or find out where it is for selection
* on the screen.
* </ul>
*
* <h4><a name="synchronization">Synchronization</a></h4>
*
* <p>
* Date formats are not synchronized.
* It is recommended to create separate format instances for each thread.
* If multiple threads access a format concurrently, it must be synchronized
* externally.
