java - enum.values() - is an order of returned enums deterministic -
i have enum some_enum
:
public enum some_enum { en_one, en_two, en_three; }
will some_enum.values()
return enums in order of enum declarations: en_one, en_two, en_three
? rule or not guaranteed not changed in next jdk releases?
the java language specification uses explicit language:
@return array containing constants of enum type, in order they're declared [source]
so, yes, returned in declaration order. it's worth noting order might change on time if changes class careful how use this.
