11/24/2017 at 11:55PM

Objective:

Write a program where a user populates a collection of various cats and dogs.  The user should be able to specify which type they wish to enter, and then are prompted with the pertinent information for every type of pet.    

Requirements:

The structure of the program should follow this UML class diagram.

Notes

• Animal collection is a collection of Animals (the * means "many")
• AnimalFrontEnd is the driver (it uses 1 Animal Collection)
• The other 7 classes are in related by inheritance

You may also include helper methods and attributes that are not noted in the class.

Additional Notes:

• The weight for animal should be strictly greater than 0
• The mood for a cat should either be “sleepy”, “playful”, or “hungry”
• The energy level for a dog should be between 0 and 100 inclusively
• The type of house cat should one of the following
• Short Hair
• Bombay
• Ragdoll
• Sphinx
• Scottish Fold
• The type of domestic dog should be one of the following
• Retriever
• Terrier
• Husky
• Yappy
• Mutt
• In addition to what’s specified in the UML diagram, the classes, Animal, Cat, Dog, HouseCat, Leopard, Domestic Dog, and Wolf must have
• Constructors (Both default and parameterized)
• Accessors and Mutators
• A toString method
• An equals method
• In addition to what’s specified in the UML diagram, AnimalCollection only needs a default constructor which will set the array of animals to some constant default size. Also no Accessors or Mutators.
• Remember the block arrows are the “is a” relationship so it means inheritance
• The line arrows are the “has a” relationship so it contains one or more instances of that class
