initialize_methods.rb

## Here is a basic class, with a basic
## initialize method that takes a name
## argument

class Employee
  attr_accessor :name
  def initialize(name)
    @name = name
  end
end

## Now we create a new Employee object, with 
## the name already initialized
e = Employee.new(“Michael Koby”)
e.name # => "Michael Koby"

## Now we'll edit the Employee class to add
## and read only age property and change the
## initialize method to also take an age argument

class Employee
  attr_reader :age
  def initialize(name, age)
    @name = name
    @age = age
  end
end

## Now we create a new Employee object, with the 
## name and age initialized
e = Employee.new(“Michael Koby”, 32)
e.name # => "Michael Koby"
e.age # => 32
