java - Common Data Utils is there such a thing? -

i find myself quite in development doing things creating constants/enums mutual info states, state abbreviations, countries, languages, mime-types, time_zones...etc...etc...

is there project out there has collection of these things? i've seen them scattered in different packages, thought handy pull in bundle covered 80% of needed.

javax.activation.mimetypesfiletypemap , friends standard library dealing mime types.

java.util.timezone can used getting access available time zones.

java.util.locale can used access country related information.

know thy java libraries!
