While there are plenty of places on the web that talk about Ruby Arrays and Ruby Classes, I never have found one that just explained how to use a Class as an Array. So I thought I would post one for those who might want something simple to reference

First, the sample code:

class Test
  @dd = Array.new
  def initialize
    @dd = loadArray()
  end

  def [](a)
    @dd[a]
  end

  def []=(a, b)
    @dd[a] = b
  end

  def list
    @dd.each do |i|
      puts i
    end
  end

  def sort
    aa = Array.new
    aa = @dd.sort
    @dd = aa
  end

  private

  def loadArray
    rr = Array.new
    rr << "one"
    rr << "two"
    rr << "three"
    rr << "four"
    return rr
  end
