Objects and Classes

Objects and Classes

1. Classes: are an oop tool that enables programmers to create the abstraction of a problem

   • 3 things to consider when writing a class: class name, the fields, and the methods

2. Objects: are everywhere, living and otherwise: concrete and abstract

3. A class is a blue print or a template to create objects of identical type.

4. OOP: Object-Oriented Programming

5. 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.

6. Fields: are variables, the initials of each word is capitalized following the first word

7. null: a concept referring to nothing

8. Void: a method that does not return a value

9. Methods define actions that a class's objects can do.
