Subject: Newbie questions regarding getter/setter methods...

Just working my way through the pickaxe book.

If I have this class:

class Song  
  def name  
      @name  
  end  
  def artist  
       @artist  
  end  
  def duration  
       @duration  
  end  
end  

Do I also have to declare @name, @artist, and @duration within the method? Or 
are they implicitly declared by declaring the accessor methods?

What about this case?

class Song  
  attr_reader :name, :artist, :duration  
end  



In general, how do member variables work? Are they all private and require 
accessor/reader methods to be accessed at all? My background includes a little 
bit of C/C++ and Java.
 
Thanks!
