Today I learned to distinguish objects and classes:

Iā€™m pretty happy because I have learned about the different kinds of objects:

Array
set of objects, but it is also an instance of the Array class.
An array of days of the week:
array = ['monday', 'Tuesday', 'wendsday', 'thursday', 'friday']

Fixnum
It is an integer, no decimal places.
37

Float
They are numbers with decimals.
4.3

When Ruby programs the classes always start with upper case:

For example: Array, Float, Tree

When you want to create a new object in a class use: new and it will call the initialize method.
