JDK-4609228 - (cal) RFE: Provide additional local calendars in Java
Description
Currently, DateFormatSymbols supports only single era names. However, some other calendar systems require both regular names and abbreviations. For example, the current era in the Japanese imperial calendar system is "Heisei" which is abbreviated as "H" in short date formats.

Use Calendar.getDisplayNames() method.

EVALUATION Short and long era names are supported with new methods in Calendar, getDisplayName and getDisplayNames, in Mustang. But we will defer the API support in DateFormatSymbols.

EVALUATION Probably it's natural to return "Heisei" (in Kanji) as default. However, the DateFormatSymbols.getEras method returns abbreviations for the Julian calendar system. We would need to ignore consistencies amoung calendar systems. The following may be the spec. Method Julian calendar Japanese calendar ----------------------------------------------------------- getEras { "BC", "AD" } { "Meiji", ..., "Heisei" } getShortEras { "BC", "AD" } { "M", ..., "H" } ###@###.### 2005-04-05 08:09:06 GMT Another option would be to use a separator in an era String, like "Heisei;H". So if SimpleDateFormat finds ";", then "H" is the abbreviation of "Heisei". ###@###.### 2005-04-05 08:16:36 GMT
