enum.values() - is an order of returned enums deterministic

I have an enum something like below :-

enum Direction {

    EAST,
    WEST,
    NORTH,
    SOUTH
}

If i say values() on the Direction enum, then will the order of the value remain same all the time. I mean will the order of values will be in the below foramt always:

EAST,WEST,NORTH,SOUTH

or can the order change at any point of time.
