A student constructor is a specific type of constructor used to create objects representing students. It initializes instance variables related to student attributes such as name, age, grade level, etc., when creating new student objects.
An object is an instance of a class that encapsulates data and methods related to that class.
Instance variables are non-static variables declared within a class. Each instance (object) of the class has its own copy of these variables.
A class is a blueprint or template for creating objects. It defines the properties and behaviors that objects of that class will have.
