Setting attribute information

Imagine that a person not only needs a name but also a password. However, let’s also imagine that, at the time of the creation of a new person instance, this password is not yet known.

class Person
  def initialize(name)
    @name = name
  end
  def name
    @name
  end
  def password=(password)
    @password = password
  end
end
