Classical Inheritance in Ruby

For programmers who are new to Object Oriented Programming, the ideas behind classical inheritance can take some getting used to. This article walks you through the syntax of defining class inheritance in Ruby with explanations of each OOP feature along the way. You will have created many inheriting classes and used them in Ruby code by the end of this exercise.

Create a new Ruby code file and copy the code examples into it as you go. Run the file with the provided driver code and read the output. Try writing your own driver code to try things out new concepts as they're introduced.

# A SIN is 9 digits and we are assuming that they must have dashes in them
def has_sin?(string)
  !!(string =~ /[ ]\d{3}-\d{3}-\d{3}$/)  
end

puts "has_sin? returns true if it has what looks like a SIN"
puts has_sin?("please don't share this: 234-604-142") == true
