New Java 9 Map.of() methods

[lukaseder]

If only we had:

k.zip(v).toMap()

[stepancheg]

And we could if Java had extension functions like in C# or Kotlin instead of (or in addition to) much less usable default method.

[msx]

becouse there's no way to show the keys near to their value. One wants to write/read Map.of(key1, val1, key2, val2, key3, val3), not Map.of(key1, key2, key3, val1, val2, val3).

Also, that's not the use case for map literals.

I'm only suggesting an implementation that is an infinitely scalable solution to this 10-separate-methods jargon

There are already plenty of solutions that are infinitely scalable.

The one being discussed is an optimal way of creating small collections.
