In this document, I will show how to create a simple payroll program for Employees that exhibits Object-
oriented programming and good practices in structuring code. In this example, I will show how to
properly use packages to separate different behaviors and functionalities to make the program modular,
easy to read, and maintain.
So first we will create a class of Employee that will contain attributes and methods that will be used to
build the fundamentals of the program.
As seen in the screenshot I created three packages that different names, models, repositories, and
services. Basically, the model will hold classes that define the Employees like what are the attributes of
an employee, and other types of employees that can exist like full-time and part-time.
