Write the SmartPhone Class you outlined. This inherits from Phone class, so be sure to include the inheritance. Do not include the properties and methods from your Phone Class in SmartPhone Class, that is point of inheritance! Do not forget your subclass-specific properties and subclass-specific methods to get and set those properties (getters and setters). You will have additional methods after the getters and setters, but only for SmartPhone methods defined in your Phone Classes Diagram.
