Polymorphism is the ability of an object to take on many forms. It allows objects of different classes to be treated as the same type.
Polymorphism is a fundamental concept in object-oriented programming.
It allows a single interface to be used for different types of objects.
Polymorphism is achieved through method overriding and method overloading.
Example: A base class Animal can have derived classes like Dog, Cat, and B...
Runtime polymorphism is the ability of a method to be dynamically bound at runtime based on the type of the object.
It allows a subclass to provide its own implementation of a method that is already defined in its parent class.
It is achieved through method overriding.
The decision of which method to execute is determined by the actual type of the object at runtime.
It enables code reusability and flexibility in object-ori...

Generic collections provide type safety and reusability in software development.
Generic collections allow us to store and manipulate objects of any type in a type-safe manner.
They provide compile-time type checking, reducing the chances of runtime errors.
They promote code reusability by allowing the same collection to be used with different types.
Generic collections improve performance by eliminating the need for boxin...
