Minecraft on nintendo switch which version?

Is Minecraft on the nintendo switch the Pe version or the Java version

The Java version is only PC, bedrock version Komsole and pe for cellphone, so I would appreciate bedrock

But just have a look

Bedrock is the same as Pocket

Pocket is the same as Bedrock and since Pocket Edition means "on the go", I think that the Nintendo Switch is the Bedrock / Pocket Edition.

Could I also be on pe server?

Yes, but then you will probably have to sign in with Xbox Live (Microsoft account)
