Ruby Class Members: Getter & Setter

The simplest example of read_attr, write_attr in a class.

class Person  
  attr_reader :name, :age   
  attr_writer :name, :age   # creates the setter methods       
    
  def initialize(name)  
    [@name](http://twitter.com/name) = name  
  end  
endmike = Person.new('Mike')   
mike.age = 20               # calling setter method  
mike.age                    # calling getter method, returns 20
