Class: code that specifies the data attributes and methods of a particular type of object
Instance: object created from class

- ‘-’ is private, ‘+’ is public
Benefits of OOP
- Reusability
- Extensibility
Encapsulation: combine data and procedure into a single object
data hiding: object’s data attributes are hidden from code outside the object and access is restricted to object’s methods
polymorphism: object’s ability to take different forms
