Object oriented programming

OOP concepts:

• Encapsulation - make attributes private and expose only intended behaviors as methods
• Abstraction - expose only methods the user needs to know and hide away (abstract) any unnecessary implementation details
• Inheritance - child classes get access to methods and attributes of parent class
• Polymorphism - same method name can be implemented differently in different child classes
