Develop a class diagram for a Message class for a cell phone company. Include

generalizations for child classes TextMessage, VideoMessage, and VoiceMessage.

The Message class has attributes of account number and price. In addition it has the methods

getInfo(accountNum) and calcPrice().

The subclasses each have one additional attribute of thier own. TextMessage has

characterLength, VideoMessage has messSize and VoiceMessage has numMinutes.

Each subclass overrides the methods of the superclass with their own. No getter or setter

methods need to be documented.

Use UMLet to draw the diagram, then copy and paste (or export an image and import) to a

word processing document. Don't forget your name and other required info at the top of the

page.

could i get a complete answer to this, diagram and all connected, and how i would go about to connecting the diagrams.
