Join Kevin Skoglund for an in-depth discussion in this video Defining and using classes, part of Ruby Essential Training.
In this movie, we're going to be looking at classes.…Classes are the backbone of object-oriented programming, because classes define objects.…They tell what an object is and they define what an object can do.…Now we've been working with objects already.…We've seen that pretty much everything in Ruby is an object.…But those are Ruby's objects, the ones that are predefined for us.…This is going to be where object- oriented programming really begins for us,…because now, we're going be able to write our own classes that will define our own objects.…In order to get started with that, we first need to see how to define a class,…and the syntax is very simple.…
It's just class and end with the definition of our class in the middle, very…similar to what we had when we had methods, we had def and end, now it's class.…The one big difference though is the naming of the class.…Methods were all lowercase with underscores between the words.…Class names are going to be what we called CamelCase.…We call it CamelCase because it has the humps in the middle like that capital N.…

Q: You mention e-texteditor.com as a place to get a Windows "sister" version of TextMate. However, e-texteditor.com looks like a Chinese auto website. Are there any other alternatives?
A: E-texteditor.com appears to have gone out of business. On Windows, you should use Sublime (<a target="_blank" href="http://www.sublimetext.com/">http://www.sublimetext.com/</a>) or Notepad++ (<a target="_blank" href="http://notepad-plus-plus.org/">http://notepad-plus-plus.org/</a>) instead.
