Learning about instance variables and don't understand why the
instance variable "name" in the code example below is not visible
where as "title" is. Could someone explain this to me and why I hadto
use the "self.get_name()" method (which I don't understand since I
pulled it off the net) to get the value out of name?
Thanks
-------------------------------
class InstanceVariables
@name = "Steve"
def initialize()
@title = "Software Eng"
end
def self.get_name
@name
end
def get_name
self.class.get_name # Why can't I just return @name?
end
def get_title
@title
end
def show_vars
puts "name: #...@name, title: #...@title" # name is not set, at least
that I can tell.
end
end
------------------------
obj1 = InstanceVariables.new
puts obj1.get_name()
puts obj1.get_title()
obj1.show_vars()
------------------------
Steve
Software Eng
name: , title: Software Eng
