What is the polymorphism?

Polymorphism is a fundamental concept in object-oriented programming (OOP) that allows objects of different classes to be treated as objects of a common superclass. It enables one interface or method to be used for a general class of actions. In simpler terms, it means that objects of different types can be used interchangeably when they share a common interface or base class, allowing for more flexible and reusable code. Polymorphism is often achieved through method overriding and interfaces in languages like Java and C++.

Polymorphism is one of the most important concepts in OOP. It describes the ability of something to have or to be displayed in more than one form. The different forms arise because these entities can be assigned different meanings and used in various ways in multiple contexts.
