11.2.3. Polymorphism

Try these first

1. 1.

   What is polymorphism in object-oriented programming?

   Hint

   Think about how objects can behave differently based on their class.

2. 2.

   What is the difference between compile-time and runtime polymorphism?

   Hint

   Consider when each type of polymorphism is resolved.

3. 3.

   What is polymorphism?

   • A method of overloading functions
   • An object-oriented feature allowing multiple forms of behavior
   • A way to execute many functions at once

   Hint

   Remember it allows one interface to be used for different data types.

4. 4.

   True or False: Runtime polymorphism is achieved through method overloading.

   • True
   • False

   Hint

   Differentiate between method overloading and overriding.

5. 5.

   Design a Java program that includes multiple classes where method overloading and overriding are demonstrated.

   Hint

   Use a base class for geometric shapes with an `area` method that is overloaded.

6. 6.

   Explain how polymorphism could lead to better software design practices.

   Hint

   Think about scalability and adaptability in programming.
