OOP stands for Object-Oriented Programming. objects: So, a class is a template for objects, and an object is an instance of a class. Classes and objects are the two main aspects of object-oriented programming. Procedural programming is about writing procedures or methods that perform What is Object? The most common use of polymorphism in OOP occurs when a parent class reference is used to refer to a child class object. An object stores its information in attributes and discloses its behavior through methods. Method overloading is a case of static binding and in this case binding of method call to its definition happens at the time of compilation.
