/**
* {@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.
