To create a new class, you use the class keyword:
class Employee # code goes here. end
Previously we mentioned that variable names always start with a lower case. However in the case of classes, the convention is that class names always starts with an upper case, and it follows the CamelCase style. The convention also states that accronyms that are in uppercase too. Here's an example:
class XMLReaderAndWriter # code goes here. end
In ruby you have a special keyword called "new" which is used to create an object from a class (i.e. instantiate a class), e.g.:
NewObject = ClassName.new
NewObject = Employee.new
The "new" keyword will automatically trigger the class's "initiliaze" method. The initialize method is the equivalent to c#'s constructor method.
