Synchronous and Asynchronous method in an Interface vs in a Class?

Question

I am working on a project in which I am supposed to make a client and the role of that client is to construct a url basis on input passed and make a REST call on the right server.

And they can do it in two ways, either making a synchronous call or making an asynchronous call. So now I am not sure what is the right way to do this?

Should I make an interface for this with two methods synchronous and asynchronous method and a class that will implement this Interface or should I just make a simple class with these with these two methods inside that?

What is the better approach?

Answer 1

I would not put both methods into the interface, just the synchronuous one.Then imagine N different implementations which really only care about getting the data. All of them can likely be wrapped into a single asynchronuous wrapper class. No need to force each implementation to reinvent the asynchronuous behaviour.
