Question
Utilizing polymorphism, construct a class hierarchy that totals up feeding history of 4 animal types (elephant, dolphin, lion, and beaver).
You must at a minimum include the following methods:
getAnimalType (Returns the animal’s type. Should return “Elephant”, “Lion”, etc.)
getAnimalName (Return animal’s name, not what animal type it is. For instance, “Simba”, “Dumbo”, etc.)
getAnimalLocation (returns the animal’s location in the zoo. For instance, “Lion Cage 1”)
getFoodTypes (Returns a list of the types of food the animal eats and the unit the food is measured in (HINT: Enumerations may help))
addFeeding (this will take in the type and amount of food fed)
getFeedingTotals (this returns a list of the animal's total food intake. For Dumbo in the table above, this would be 80 lbs of hay and 5 lbs of peanuts)
Construct a tester program that tests your class hierarchy (no user input necessary). Your program must have at least one of each animal instantiated. At a minimum, your tester program must feed each of the animals and then print out records of their feedings. Each public method must be called at least once in the test.
