Use polymorphism using interfaces: Computer Science Principles: Programming

Learn to type variables to various different classes. First, you can type a variable to a single class. Next, you can type a variable to a superclass, which allows any subclass to be used for the variable. Finally, you can categorize classes using interfaces. Interfaces define methods that are present with any class that implements the interface. As a result, you can type a variable to the interface and any class that follows the interface rules can be assigned to the variable.
