Following this logic we can change hashCode() in Object to provider().
Because it will return a value, that provides a hashCode.
No the value returned _is_ a hashcode.
You are confusing returning an object that is capable of providing a
service, with asking that object to provide the service.

I still think that provider()
name is not quite good. I would name it either "service" or "provide".

They are two different things and I'm certainly not saying they are the
same.

I'm not seeing the connection with what we have been discussing
directly.
The provider() method returns an instance of a class that provides a
given service. provider() could be called serviceProvider() or
serviceImplementor() - but providor() suffices.
