Hi everyone,

I've a homework execrise about that...

1. In what situation would we use an abstract class instead of an interface?

2. In what situation would we use an interface instead of an inheriting from a superclass?

3. When is it better to use an interface rather than an abstract class?

How to think that three kinds of keywords?
Thanks
Larry
