having multiple constructors in ruby [duplicate]

Question

is there a way to have multiple “initialize” methods in ruby? For example: one method excepting one argument while another excepts three ?

Something like

 class One
  def initialize (a)
    puts a
  end
  def initialize_1 (a,b)
    puts a ,b 
  end
end

Answer 1

initialize is actually not a constructor. You can indeed have two constructors.

class One
  singletonclass.class_eval{alias old_new :new}
  def self.new a
    puts a
    old_new
  end
  def self.new_1 a, b
    puts a, b
    old_new
  end
end
