* Principles of Object Oriented Programming
  - Abstraction: finding attributes and behaviors of objects
  - Encapsulation: creating a class that has the attributes and
    behaviors
    - Information Hiding: make attributes private and make behaviors
      public
  - Inheritance:
    - create a structure (basically a tree structure) for the classes
      that we create
      the relationship between classes in the hierarchy is given by
      the phrase "is-a" or "is-an"
    - code reuse
