Both of these code examples for making class properties don't work
although they are pretty much straight out of the book "Programming
Ruby". What I am doing wrong here?

error is: undefined method `firstName' for #<User:0xb7f76b24
@firstName="Newton"> (NoMethodError)
----------------------
class User

	attr_writer :firstName

	def initialize(firstName)
		@firstName = firstName
	end
end

user = User.new('Hal')
user.firstName = 'Newton'
print user.firstName
--------------------------------

class User

	def firstName=(newFirstName)
		@firstName = newFirstName
	end

	def initialize(firstName)
		@firstName = firstName
	end
end

user = User.new('Hal')
user.firstName = 'Newton'
print user.firstName

--------------------------------
