Is class A user defined data type?

Class: The building block of C++ that leads to Object-Oriented programming is a Class. It is a user-defined data type, which holds its own data members and member functions, which can be accessed and used by creating an instance of that class.

What is meant by instance variable?

An instance variable is a variable which is declared in a class but outside of constructors, methods, or blocks. Instance variables are created when an object is instantiated, and are accessible to all the constructors, methods, or blocks in the class.

What is a static object?

What is Polymorphism in java?

Polymorphism in Java is the ability of an object to take many forms. To simply put, polymorphism in java allows us to perform the same action in many different ways. Polymorphism is a feature of the object-oriented programming language, Java, which allows a single task to be performed in different ways.
