- User interface classes. These classes are designed for Human Computer Interaction(HCI).
- Business domain classes.
- Process classes.
- Persistence classes.
- System Classes.
What is class explain?
In object-oriented programming , a class is a template definition of the method s and variable s in a particular kind of object . Thus, an object is a specific instance of a class; it contains real values instead of variables. A class can have subclasses that can inherit all or some of the characteristics of the class.
Does the middle class exist?

A method is a procedure associated with a class and defines the behavior of the objects that are created from the class. A function is a combination of instructions that are combined to achieve some result.
Which is the main aim of OOP programming?
The main aim of OOP is to bind together the data and the functions that operate on them so that no other part of the code can access this data except that function. 1. Class: A class is a user-defined data type. It consists of data members and member functions, which can be accessed and used by creating an instance of that class.
How are class templates declared in object oriented programming?
A class template is declared using the template keyword followed by angle brackets<> enumerating the list of formal parameters with the typename keyword. This entry informs the compiler that it deals with a generic class with the T formal parameter defining a real variable type when implementing a class.
