Map a Collection

Hi,

I wonder why Map is considered Collection eventhough it does not implement Collection interface and whose behaviour is quite different from List or Set.

Please advise

Besides that, I think maybe you read about a Map being considered a collection (with small 'c')
In that sense, a map is indeed a collection of key-value pairs (or a set of key-value pairs, but again also with a small 's')

Any book on java deals with Collection related chapter with Map right apart from Set and List.

I mean to say small 'c'
Big C is for interface right which is only being implemented by List and Set as attached

Well, then you got the answer: a map is a collection of key-value pairs
