Exam 1z0-808 topic 1 question 159 discussion

AB is the good answer

A and B only

sorry for my answer i have tested A and C is good answer

in this case the only two good ones represent its A and B, the Implementation of an abstract method in the child class can be private in note case it does not prevent the compilation, instead the method revolve and declared protected so the child class this method can be declared minimum protected or lower public, thus the answer and A, B

The answer would be BC or AC.

The answer whould be BC or AC. Both A and B are correct answers unfortunately. Note that in these options what is being analyzed is an override and not an implementation of an abstracted method. The oracle documentation states that the access modifier in this case could be the same or allow for greater visibility, not less. Which makes options A and B correct. If the question is correct, it remains to be seen what is the best practice or convention in this regard. https://docs.oracle.com/javase/tutorial/java/IandI/override.html About the answer: I choose AC. Whereas, the abstract class is a pseudo-model to follow. I would keep the same access modifier already informed in it. Another no less relevant issue is having confidence in this simulated exam material that being the knowledge base for us. We wait for new comments in this forum to improve the accuracy in the answer.

The question was asked wrong, because in addition to answers A and C being correct, B is also correct. So both AC and BC are correct, because in inheritance you can put a view pattern bigger than the parent class, you just can't put it smaller. Attention to the question because she didn't talk about independent changes so it can't be AB.
