Abstract classes, Interfaces, and Patterns - slide 11 : 37

Interfaces

An interface corresponds to a fully abstract class. No matters of substance is found in the interface, just declarations of intent

An interface describes signatures of operations, but it does not implement any of them

Interfaces
- Classes and structs can implement one or more interfaces
- An interface can be used as a type, just like classes
  - Variables and parameters can be declared of interface types
- Interfaces can be organized in multiple inheritance hierarchies

Sketches of the classes Vehicle, FixedProperty, Bus, and House - for the exercise.
