About Question enthuware.ocpjp.v7.2.1316 :

I just did two tests back to back and I apologize if this is exhaustion-induced stupidity.

If we had objects instead of primitives in the method returns, say Integer and Long on the return types, would the last answer be a correct overriding of the method with a covariant return type Short replacing Long ?

Thanks!

No, because Long doesn't extend Short.

Thanks. Now when rested I see how far off I was!
