Question 158

Given:

and

Which is the correct implementation of the getRatings method in the Football subclass?

The subclass getRatings method uses public.getRatings() to call the base class method but uses its own named fields in the implementation.

The subclass getRatings method implementation directly accesses the fields in the Sports superclass.

The subclass getRatings method uses new.getRatings() to call the base class method but uses its own named fields in the implementation.

The subclass getRatings method uses super.getRatings() to call the base class method but uses its own named fields in the implementation.

Correct Answer: D

To correctly implement the getRatings method in the Football subclass while calling the base class's method, the appropriate approach is to use super.getRatings(). This syntax ensures that the method from the superclass (Sports) is invoked, while the subclass (Football) can still utilize its own fields in the method implementation. The other options either suggest incorrect syntax (like new.getRatings() or public.getRatings()) or imply direct field access without calling the superclass method.

Discussion

OmnisumemOption: D

AI answered: The correct implementation of the getRatings method in the Football subclass is: D. The subclass getRatings method uses super.getRatings() to call the base class method but uses its own named fields in the implementation. Explanation: Using super.getRatings() allows the Football subclass to call the getRatings method defined in the Sports superclass. The subclass can then use its own named fields and logic in the implementation of the method while still leveraging the functionality provided by the base class.
