Hi Juan,

First of all, congratulations for your great article. I just read it and kudos to you for that. I don’t think I’m saying anything different than you though. I appreciate your comment, but I’m afraid maybe this is just a communication issue and semantics. I’ve studied several examples of this and using interfaces is just one of them. Thank you for your comment and I’m glad to see that we don’t disagree on this.

Another thing that would help, if you want to explain your point clearly, is to provide your own implementation and then we can compare our notes. My example is also a Java version of what AC has done in his own presentation. I have put the links on my repo to his video on Youtube. I still don’t see any difference between what I did in Java and what AC did in C#. There are many implementations like this on the web anyways and so this makes it difficult to understand your point exactly. This why I think this may only be about semantics and that maybe you are only expecting me to say a certain order of words.

Thank you anyways!
Cheers!
João
