How to run a class with an unknown number of String parameters?

Question

I am working on an API that should provide easy access to a number of resources based on a remote web service.

Some of these remote resources require special parameters for transmission before communication. For example, for one of them it is required to transfer a key pair of the developer, another - a key pair and a unique identifier. The third does not require these parameters at all. Now I work with three services, but their number can be increased.

For each web service, I have a corresponding implementation of my API. The problem is that I don’t know how to imagine the ability of my API to transmit an unknown number of rows with unknown values.

Some of my suggestions are:

1.

ServiceFactory.createService (ServiceEnum type, Properties keys);

2.

ServiceFactory.createService (ServiceEnum type, ServiceParams params);

ServiceParams - -. :

public class ServiceHelper {

   public static ServiceParams createFirstServiceParams (String secretKey, String publicKey);

   public static ServiceParams createSecondServiceParams (String secretKey, String publicKey, String uid);

   public static ServiceParams createThirdServiceParams ();
}

3.

ServiceFactory.createService (ServiceEnum type, String ... params);

: . (, ServiceParams).

4-6:
