var with generic enumMap declaration

Question

Is this declaration

// version 1
EnumMap<Type, EnumSet<Part>> types = new EnumMap<>(Type.class);

the same as this:

// version 2
var types = new EnumMap<Type, EnumSet<Part>>(Type.class);

I think it's the same, because I can also write this:

EnumMap<Type, EnumSet<Part>> types = new EnumMap<Type, EnumSet<Part>(Type.class);

and therefore this:

// version 2
var types = new EnumMap<Type, EnumSet<Part>>(Type.class);

Are there any differences in version 1 and version 2? Which should I prefer?

*"Is this declaration...the same as this..."* I'm not versed enough in Java's `var` to say for *sure*, but...what else could either of them mean? :-) — T.J. Crowder, Jun 08 '19 at 13:37
When you have to ask such questions, you should prefer variant 3. — Holger, Jun 11 '19 at 15:57

Concise answers are great. I think you are over-doing. By far. – GhostCat Jun 08 '19 at 14:08
