simulating dice with different numbers of sides (six, ten, and twenty) and a class for managing a collection of these dice.

Class is a set of object which shares common characteristics/ behavior and common properties/ attributes. Object is a basic unit of Object-Oriented Programming and represents real-life entities. A typical Java program creates many objects, which as you know, interact by invoking methods.

A class is a blueprint for the objects which defines a template to be used to create the required objects. The objects are created from the Kotlin class and they share the common properties and behaviours defined by a class in form of data members (properties) and member functions (behaviours) respectively.
