Objects and Classes

Classes: are an oop tool that enables programmers to create the abstraction of a problem
1. 3 things to consider when writing a class: class name, the fields, and the methods
Objects: are everywhere, living and otherwise: concrete and abstract
A class is a blue print or a template to create objects of identical type.
OOP: Object-Oriented Programming
Ex: Having an employee class that has age and position as fields, all employee objects created out of this class will have age and position as fields.
Fields: are variables, the initials of each word is capitalized following the first word
null: a concept referring to nothing
Void: a method that does not return a value
Methods define actions that a class's objects can do.
