 __Polymorphism comes to play in Anonymous Inner Class__ as in the above example, we're using a superclass reference 
 variable type to refer to a subclass object. So, we need to keep in mind some points: 
    
-
+* You can only call methods on an anonymous inner class reference that are defined in the reference variable type. So,
+in the above code, you cannot call `p.push()` as `p` is a reference variable of type `Popcorn` and `Popcorn` class does 
+not have any method named `push()`.
