Final answer:
A subclass of a superclass with the Comparable interface and compareTo method will inherit the Comparable interface and the compareTo method. The correct answer is d. Inherit. The compareTo method often should be overridden for correct subclass-specific behavior.
Step-by-step explanation:
Subclasses of a superclass with Comparable and compareTo will automatically inherit Comparable and inherit the compareTo method. The correct answer is d. Inherit.
When a subclass is created from a superclass that implements the Comparable interface, the subclass inherits the superclass's implementation of the compareTo method. However, to maintain correct behavior with respect to the ordering, the compareTo method should be overridden in the subclass if its comparison criteria differ from that of the superclass. In cases where the comparison criteria are the same, the inherited method may be used without overriding.
