You are to refactor the following classes. Read through all of the classes provided below and decide which ones are similar enough that they would belong in the same class hierarchies. Then find a meaningful way to build the hierarchies keeping in mind the following concepts:
- Subclasses should always possess the "IS-A" relationship with the corresponding superclass.
- All commonality should be placed as high in the hierarchy as possible.
- Although full OO classes will have behaviors, some of the classes provided below do not have any to reduce complications. Do not add behaviors (or any additional attributes) to these classes.
- You should add superclasses as needed. If one class inherits from another, clearly indicate the class that is being inherited from and clearly indicate which attributes and behaviors are being inherited and which are not.
