Date object or

*
* {@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. * *
{@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. * *
To format a date for the current Locale, use one of the * static factory methods: *
* {@code
* myString = DateFormat.getDateInstance().format(myDate);
* }
*
* 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. *
* {@code
* DateFormat df = DateFormat.getDateInstance();
* for (int i = 0; i < myDate.length; ++i) {
* output.println(df.format(myDate[i]) + "; ");
* }
* }
*
* To format a date for a different Locale, specify it in the * call to {@link #getDateInstance(int, Locale) getDateInstance()}. *
* {@code
* DateFormat df = DateFormat.getDateInstance(DateFormat.LONG, Locale.FRANCE);
* }
*
*
* If the specified locale contains "ca" (calendar), "rg" (region override), * and/or "tz" (timezone) Unicode * extensions, the calendar, the country and/or the time zone for formatting * are overriden. If both "ca" and "rg" are specified, the calendar from "ca" * extension supersedes the implicit one from "rg" extension. * *
You can use a DateFormat to parse also. *
* {@code
* myDate = df.parse(myString);
* }
*
* 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: *
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. * *
You can also use forms of the parse and format methods with * {@link ParsePosition} and {@link FieldPosition} to * allow you to *
* 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. * * @implSpec *
