Haha, this is a classic Java trick question. I'm going with C. The output will just be 'Dog' twice, because that's what the printAnimal() method is hard-coded to return.

No way, the answer has to be D. The first call to printAnimal() will return 'Cat', but the second call will return 'null' because the animal reference is null.

I think the answer is B. The code fragment is trying to access a member of a null object, which will throw a NullPointerException.

I disagree, I believe the answer is D) Cat null because the second element in the array is null.
