Subject: Re: different methods for initializing one object?

Thanks for all your answers, in fact, my class was already written with
the last mentioned code method.

class Point

  attr_accessor :abs, :ord, :name, :cart

  def initialize(abs,ord,name="")
    @abs = abs
    @ord = ord
    @name = name
    @cart = true
  end

  def to_s
    "#@name : (#{@abs}, #{@ord})"
  end

  def ==(unPoint)
    unPoint.abs = abs and unPoint.ord = ord
  end

  def Point.new_polaire(rho, theta, name)
    @cart = false
    @name = name
    unPoint = new(rho*cos(theta),rho*sin(theta),@name)
    return unPoint
  end

end

....but I dislike the calling syntax. I thought it was possible to write
several constructors calls like in Java, ie :

    void Move(Vector2D vector) {
        center.x += vector.x;
        center.y += vector.y;
    }

    void Move(double x,double y) {
        center.x += x;
        center.y += y;
    }

So, my idea was bad : Ruby is not Java !
