When should I use abstract classes in programming?
An example of an AI chatbot conversation about when to use abstract classes in programming.
When should I use abstract classes in programming?
Abstract classes are used when you want to define a base class that cannot be instantiated on its own, but can provide a common interface for derived classes.
Can you give me an example of when to use one?
Sure! If you have a base class called 'Animal' with an abstract method 'makeSound()', you can create derived classes like 'Dog' and 'Cat' that implement 'makeSound()' differently.
What are the benefits of using abstract classes?
They promote code reusability, enforce a contract for subclasses, and help in organizing code by defining a clear hierarchy.
Are there any downsides to using abstract classes?
Yes, they can introduce complexity and may lead to a rigid class structure if not used judiciously.
