4,779 Pointsinstance varible
Hii, Didn't understand the methods in the answer:
def initialize (title) @title=title end def title @title end
a. the second line is assigning the global varible to a local variable? what is the importance of @? b. the second methode means: "when calling the method title (Which belongs only to the specific class, I would guess), return the local varible"? should be there a return or something?
Thank you!
class Name
def initialize (title)
@title=title
end
def title
@title
end
def first_name
"Metal"
end
def last_name
"Robot"
end
end
name=Name.new("Dr.")

2,941 PointsThe @ means the variable is an "instance" variable. So every time you do:
Name.new
You will be creating a new Name object and inside that object will be a title field. So in the second method here:
def initialize (title)
@title=title
end
def title
@title
end
You are returning the value of @title, or that specific name object's title. The initialize method sets @title with a starting value.
