Any way to stream a map like “(k,v)” instead of working with (entry)?

Question

Basically I look for a way to avoid working with

entry -> entry.getValue

and

entry -> entry.getKey

Answer 1

No, there's no way to do this; Stream only works with a single element type. There's no way around the getKey and getValue approach.

(Streaming over the keys and calling get doesn't actually seem to be any better from your perspective, and it's likely to be strictly less efficient.)
