Class

A class is a piece of code within a program that functions as a template or blueprint for creating multiple instances of a particular object.

The template provides initial values and behavior for each of these instances. Each instance is an object itself.

Suppose we want to create a Cat class with three instance variables:

• @cat_name
• @cat_color
• @cat_age

class Cat
   def initialize(name, color, age)
      @cat_name = name
      @cat_color = color
      @cat_age = age
   end
end

Now we can create a bunch of objects based off of the Cat class:

mochi = Cat.new("Mochi", "Gray", 2)

bean = Cat.new("Bean", "Black/Gray", 6)

femi = Cat.new("Femme en Noir", "Black/White", 9)
