Notes on Interfaces vs Abstract Classes
Interface should be preferred over abstract classes for the following reasons:
Existing classes can easily implement new interfaces for added functionality, however existing classes that already extend super classes can't inherit from a new class since multiple inheritance is prohibited in Java.
Interfaces can be used for mixin types. A mixin is a type that ...
