1. Encapsulation Inheritance PolyMorhpism
Object-Oriented Programming Principles

2. Create New Project
OOPPrinciples

3. Animal Class Fields: Methods: name dangerous toString()
getters and setters
says(), which returns a string of what noise the animal makes

4. Three Subclasses Dog, Cat, Sheep… Whatever as long as you have three
Each should subclass Animal…
class Dog extends Animal { }
Override the says() method for each new class

5. UML
Create UML diagram showing inheritance hierarchy

6. OOPPrinciples Main Create a new empty Animal[] array of ten Animals
Populate it with random animals of the subclasses that you created, ie Dog, Cat, Sheep, etc (ie you should not know which animals are which)
Loop through the array and for each animal print the return value of the says method

7. Notes Make notes on which part of your code demonstrates
Encapsulation
Inheritance
Polymorphism
Write a concise definition for each
Write a short paragraph outlining the advantage(s) of each

8. Key vocabulary encapsulation, inheritance, polymorphism
class, superclass, subclass, extends
inheritance hierarchy (cf containment hierarchy)
override
