Question 1

What is polymorphism in OOP?

  • A type of variable
  • The ability to redefine methods in subclasses
  • A technique to write more complex problems

💡 Hint: Focus on the ability to change or redefine functionality.

Question 2

True or False: Method overloading occurs when a subclass overrides a method.

  • True
  • False

💡 Hint: Think about what happens in the same class versus in subclassing.

Challenge Problems

Push your limits with challenges.

Question 1

Create an object-oriented model simulating a library system where different media types (books, DVDs, magazines) inherit from a common Media base class, using polymorphism. Include overloaded methods for checking out each media type with different parameters.

💡 Hint: Think about how each type of media has common properties but behaves differently.

Question 2

Design a class hierarchy for an animal shelter, using polymorphism to create a base class 'Animal' with a method 'makeSound()' overridden in subclasses like 'Dog' and 'Cat'. Implement method overloading to handle different types of sounds.

💡 Hint: Consider how real animals have unique sounds but still belong to a common category.
