ruby : if i declare a variable in a method does another method in the same class know it exists?

Question

If i have a method called roll (as in a dice) and it has a variable called number.

can another method in the same class called stats use that variable in it ??

Answer 1

You mean like this?

class Die
  def roll
    @number = 5
  end

  def stats
    puts @number
  end
end

d = Die.new
d.roll
d.stats # prints 5
