What are the best practices for using polymorphism in programming?

What are the best practices for using polymorphism in programming?

Polymorphism allows methods to do different things based on the object it is acting upon. Best practices include using interfaces and abstract classes to define common behaviors.

Can you give an example of polymorphism in action?

Sure! For instance, if you have a base class Animal with a method makeSound(), subclasses like Dog and Cat can implement this method differently. When you call makeSound() on an Animal reference, it will execute the appropriate subclass method.

What are the advantages of using polymorphism?

Polymorphism enhances code reusability and flexibility, allowing you to write more generic and maintainable code. It also supports the implementation of dynamic method resolution.

Are there any common pitfalls to avoid with polymorphism?

Yes, common pitfalls include overusing polymorphism, which can lead to complex code, and not properly managing type hierarchies, which can cause runtime errors.
