Answer:
"this" keyword representing the class object itself.
Step-by-step explanation:
Object-oriented programming concept emphasizes on using blueprints representing the structure of a data collection type to continuously create an instance of that data structure. The instance of that object is called a class object. It is used in database management systems to populate the database.
Functions defined in the class objects are called methods and are used specifically by the class instance to modify the data content of the class object defined.
When a member of a class is referenced in the class, it can be accessed with the "this" keyword. At an instance of the class object, the variable holding the object should be called to get the class content because of the "this" keyword binding the instance of the object to the method.
