For this problem you are to join the following classes into a hierarchy (use the UML diagrams from Module 2 to get started) SpaceCraft - Superclass SpaceFighter - Subclass Tanker - Subclass Transporter - Subclass Drill - Subclass Carrier - Subclass If the sub classes are shown on the same level, then they share a parent class. If the parent class has the same attributes as the sub class then you can remove those attributes from the subclass. If the super class was not included in module 2, then it should only contain attributes or functionality that are contained in all subclasses. If the class is new for this module, please come up with 2 unique attributes of your choice, and 1 piece of functionality.
