What is method overriding?
Think about how subclasses can provide specific behaviors.

Consider an animal's sound when the actual object is a Cat.
What is the primary benefit of runtime polymorphism?
Consider how polymorphism helps you avoid repeating yourself.
True or False: Method overriding allows a subclass to have a method with a different signature than its superclass.
Think about how method signatures interact between classes.
Design a simple Java application that simulates a zoo. Implement a base class Animal with overridden methods for different animal types, like Lion and Elephant. Explain how runtime polymorphism helps in managing the behaviors.
Think about how you can use a common reference type for different derived types.
How does the use of method overriding simplify code structure in an application with multiple payment methods (CreditCard, PayPal)? Outline the advantages.
Emphasize how polymorphism can reduce duplication and enhance flexibility.
