Note

For a quick review of object oriented principles:

• Abstraction: Simplifying concepts by ignoring unimportant details.
• Encapsulation: Allows you to bundle data and functions into self-contained objects, so that other objects can interact with it through an exposed interface and restricting access to the data and dictate what can be done with it.
• Decomposition: Allows you to break a problem into smaller, distinct parts.
• Generalization: Allows you to factor out conceptual commonalities.
