<p><a class="el" href="classDateFormat.html" title="DateFormat is an abstract class for a family of classes that convert dates and times...">DateFormat</a> is an abstract class for a family of classes that convert dates and times from their internal representations to textual form and back again in a language-independent manner. </p>
<p>Converting from the internal representation (milliseconds since midnight, January 1, 1970) to text is known as "formatting," and converting from text to millis is known as "parsing." We currently define only one concrete subclass of <a class="el" href="classDateFormat.html" title="DateFormat is an abstract class for a family of classes that convert dates and times...">DateFormat</a>: <a class="el" href="classSimpleDateFormat.html" title="SimpleDateFormat is a concrete class for formatting and parsing dates in a language-independent...">SimpleDateFormat</a>, which can handle pretty much all normal date formatting and parsing actions. </p>
<p><a class="el" href="classDateFormat.html" title="DateFormat is an abstract class for a family of classes that convert dates and times...">DateFormat</a> 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>
<p>To format a date for the current <a class="el" href="classLocale.html" title="A Locale object represents a specific geographical, political, or cultural region...">Locale</a>, use one of the static factory methods: </p>

<li>
SHORT is completely numeric, such as 12/13/52 or 3:30pm </li>
<li>
MEDIUM is longer, such as Jan 12, 1952 </li>
<li>
LONG is longer, such as January 12, 1952 or 3:30:32pm </li>
<li>
FULL is pretty completely specified, such as Tuesday, April 12, 1952 AD or 3:30:42pm PST. </li>
</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 <a class="el" href="classDateFormat.html" title="DateFormat is an abstract class for a family of classes that convert dates and times...">DateFormat</a> you get from the factory methods to a <a class="el" href="classSimpleDateFormat.html" title="SimpleDateFormat is a concrete class for formatting and parsing dates in a language-independent...">SimpleDateFormat</a>.

<p>Formats a date into a date/time string. </p>
<p>This is an abstract method which concrete subclasses must implement. </p>
<p>On input, the <a class="el" href="classFieldPosition.html" title="FieldPosition is a simple class used by Format and its subclasses to identify fields...">FieldPosition</a> parameter may have its "field" member filled with an enum value specifying a field. On output, the <a class="el" href="classFieldPosition.html" title="FieldPosition is a simple class used by Format and its subclasses to identify fields...">FieldPosition</a> will be filled in with the text offsets for that field. </p>
<p>For example, given a time text "1996.07.10 AD at 15:08:56 PDT", if the given fieldPosition.field is UDAT_YEAR_FIELD, the offsets fieldPosition.beginIndex and statfieldPositionus.getEndIndex will be set to 0 and 4, respectively. </p>
<p>Notice that if the same time field appears more than once in a pattern, the status will be set for the first occurence of that time field. For instance, formatting a UDate to the time string "1 PM PDT (Pacific Daylight Time)" using the pattern "h a z (zzzz)" and the alignment field DateFormat::TIMEZONE_FIELD, the offsets fieldPosition.beginIndex and fieldPosition.getEndIndex will be set to 5 and 8, respectively, for the first occurence of the timezone pattern character 'z'.</p>
