An example of an AI chatbot conversation about when to use abstract classes in design.
When should I use abstract classes in design?
Abstract classes are used when you want to define a common interface for a group of related classes, but you don't want to instantiate the abstract class itself.
Can you give me an example of when to use one?
Sure! If you have a class hierarchy for different types of vehicles, you might have an abstract class called 'Vehicle' with methods like 'startEngine()' that all subclasses must implement.
What are the benefits of using abstract classes?
They promote code reusability, enforce a contract for subclasses, and help in organizing code by grouping related functionalities.
Are there any downsides to using abstract classes?
Yes, they can introduce complexity and may lead to a rigid structure if overused. It's important to use them judiciously.
