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.
