Exam Tip
---------------------------------------------------

abstract methods must be implemented by a subclass, so they must be inheritable.
abstract methods cannot be private.
abstract methods cannot be final.
abstract methods may have parameters, a return type, and optional throws clause, but are not implemented.
abstract methods end in a semicolon-no curly braces.
A single abstract method in a class means the whole class must be abstract.
An abstract class can have both abstract and nonabstract methods.
