What are the best practices for using abstract classes in programming?
When using abstract classes, ensure they have a clear purpose and are not overly complex. Use them to define a common interface.
Can you give an example of when to use an abstract class?
Sure! Use an abstract class when you have multiple subclasses that share common behavior but also have specific implementations.
What are the differences between abstract classes and interfaces?
Abstract classes can have method implementations and state, while interfaces can only define method signatures without any implementation.
How do I decide whether to use an abstract class or an interface?
If you need to share code among related classes, use an abstract class. If you need to define a contract for unrelated classes, use an interface.
