Object Oriented Programming (OOP)

Abstraction

• Hide the internal working of a given system. The client needs to work only with the interfaces.
• Example: a car exposes the gas and brake pedals, but it doesn't matter to the driver what is happening on the enginer or the brake pads

Encapsulation

• Data + Functions inside a container (for example, a class)
• The data can be accessed via getters/setters to avoid exposing the information directly

Inheritance

• Allows reusing classes and avoiding duplicity

Polymorphism

• Override methods from parent classes
• The returning value must have the same shape
