 * {@icuenhanced java.text.DateFormatSymbols}.{@icu _usage_}
 *
 * 

DateFormatSymbols is a public class for encapsulating * localizable date-time formatting data, such as the names of the * months, the names of the days of the week, and the time zone data. * DateFormat and SimpleDateFormat both use * DateFormatSymbols to encapsulate this information. * *

Typically you shouldn't use DateFormatSymbols directly. * Rather, you are encouraged to create a date-time formatter with the * DateFormat class's factory methods: getTimeInstance, * getDateInstance, or getDateTimeInstance. * These methods automatically create a DateFormatSymbols for * the formatter so that you don't have to. After the * formatter is created, you may modify its format pattern using the * setPattern method. For more information about * creating formatters using DateFormat's factory methods, * see {@link DateFormat}. * *

If you decide to create a date-time formatter with a specific * format pattern for a specific locale, you can do so with: *

*
 * new SimpleDateFormat(aPattern, new DateFormatSymbols(aLocale)).
 * 
*
* *

DateFormatSymbols objects are clonable. When you obtain * a DateFormatSymbols object, feel free to modify the * date-time formatting data. For instance, you can replace the localized * date-time format pattern characters with the ones that you feel easy * to remember. Or you can change the representative cities * to your favorite ones. * *

New DateFormatSymbols subclasses may be added to support * SimpleDateFormat for date-time formatting for additional locales. * * @see DateFormat * @see SimpleDateFormat * @see com.ibm.icu.util.SimpleTimeZone * @author Chen-Lieh Huang * @stable ICU 2.0 */ public class DateFormatSymbols implements Serializable, Cloneable { // TODO make sure local pattern char string is 18 characters long, // that is, that it encompasses the new 'u' char for // EXTENDED_YEAR.
