title: Separate class for list of objects?
body: <p>I have a class in Active Record pattern. Lets call it "Car". So I have all my methods like insert, update etc but they work only on single object. What if I want to work on a list of these objects? Should I create a separate class lets say "CarCollection" that will be used to work on list of Car objects? Or should I create a method in my Car class that will return a list of Car object? I am a beginner in OOP but the second option (method that returns a list) seems kinda wrong.</p>
  
  <p>Thanks for answers.</p>
