What are the differences between class types in programming?

In programming, class types can vary significantly. Common types include abstract classes, interfaces, and concrete classes. Would you like to know more about a specific type?

Yes, can you explain what an abstract class is?

An abstract class is a class that cannot be instantiated on its own and is meant to be subclassed. It can contain abstract methods that must be implemented by derived classes.

How does an interface differ from an abstract class?

An interface defines a contract that implementing classes must follow, while an abstract class can provide some default behavior. Interfaces cannot have any implementation, whereas abstract classes can.

Can you give an example of when to use each?

Use an abstract class when you want to share code among closely related classes, and use an interface when you want to define a common behavior across unrelated classes.
