What are the differences between abstract and concrete classes?
An example of an AI chatbot conversation about the differences between abstract and concrete classes in programming.
What are the differences between abstract and concrete classes?
Abstract classes cannot be instantiated and may contain abstract methods, while concrete classes can be instantiated and provide implementations for all methods.
Can you give me an example of each?
Sure! An abstract class could be Animal with an abstract method makeSound(). A concrete class could be Dog that extends Animal and implements makeSound().
Why would I use an abstract class instead of a concrete class?
Abstract classes are useful for defining a common interface for a group of related classes, promoting code reusability and consistency.
Are there any limitations to using abstract classes?
Yes, you can only inherit from one abstract class in languages like Java, which can limit flexibility compared to interfaces.
