About Question enthuware.ocpjp.v7.2.1200 :

[Ciprian Mihalache]

Is the Statement creation necessary in the code? (Both statement and explanation)
I see it is not used, are there any side effects of creating it?

[admin]

No, it doesn't serve any purpose here. Should be removed.

thank you for your feedback!

Now I see another improvement to the question statement. As it is now, the code will not compile because the other 2 "evaluate" methods declare boolean return type but their implementation is empty. This is not the case for the explanation code (which is awesome)

[admin]

Fixed!
