We have defined a class MainClass and it contains a method super_class_method. In Ruby Inheritance is a very powerful feature, it allows us to use one class attributes like methods and variable inside another class, or in more technical word with the help of Inheritance concept one class A can inherit all the properties of class B, Ruby does not support multiple class inheritance (class A can not inherit properties of many classes like B, C, and D), this concept is useful in case we wanted to reuse the same piece of code for other places without writing the same code, or reusing the same piece of code by doing little modification in the parent class properties instead of writing complete properties. #All the initialisation will be here puts "This is the method for parent class" def initialize overRide.super_class_method.
