// 8.2. Interfaces
// An interface is similar to an abstract class, with some important differences.
// Interfaces allow us to create code organized by behavior, rather than static data.
// Interfaces can contain
// 1) Constants
// 2) Method signatures
// 3) Static methods
// 4) Default methods
// Refer to the IFeedable interface
HouseCat suki = new HouseCat("Suki", 12);
CatSitter annie = new CatSitter(suki);
annie.FeedThePet();
// Benefits of interfaces
// You can only extend one class, but you may implement many interfaces.
// You can extend a class and implement an interface at the same time.
// When you declare properties and return types to be interface types, you decouple code using your classes from the actual class types you use.
