Could you then explain the difference between service and service

you’re saying they are the same. I always thought, that they were two

They are two different things and I'm certainly not saying they are the
same.
what we are talking about service factory/supplier/consumer we separate
service from
factory/supplier/consumer. And even in
https://docs.oracle.com/javase/9/docs/api/java/util/ServiceLoader.Provider.html
<https://docs.oracle.com/javase/9/docs/api/java/util/ServiceLoader.Provider.html>
we assume that this is a provider, and using this provider you can get a
service.
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.

And that object is the service provider.
