Multiple choiceHardchapter-5-curatedpremiumoopmethod-overriding
Answer and explanation
Correct answer
A. By calling super inside the overridden method and adding new code.
Why
A subclass can maintain the contract of the superclass method by calling the superclass's method using super and then adding its own functionality. This ensures that the original behavior is preserved while allowing the subclass to extend it.
