Lecture Outline

• Finish up static methods
• Java classes do not inherit private instance fields. To make a private instance field inheritable, we swap from "private" to "protected"
• Abstract classes are a superclass (A class that is inherited from) that cannot be instantiated and is used to state or define general characteristics. Ie. you CANNOT create an instance of an abstract class
• An interfaces is an abstract class that consists of method definitions with no body (we will talk more about this on wednesday)
