In ruby I can find the class of an object by calling the 'class' method:

5.class
'foo'.class
3.14.class

How do I find the superclass?

this should work

5.class
=> Fixnum
5.class.superclass
=> Integer

You can also use ancestors method which will give you a list of all the superclasses

 5.class.ancestors
 =>  [Fixnum, Integer, Numeric, Comparable, Object, Kernel, BasicObject]

You call the superclass method on the class

2.1.2 :003 > 5.class.superclass
 => Integer

Reference

Class#superclass
