When using a HashSet, it is important to override both the hashCode and equals methods defined in the Object class to ensure that objects are properly compared and stored in the HashSet. By overriding only one of these methods, it is possible for objects that are equal according to one method but not the other to be considered distinct, leading to unexpected behavior. The clone method is not related to HashSet and does not need to be overridden.
