CASE STUDY: A PAYROLL SYSTEM In this project, students are to use Java to develop a payroll software to assist in paying the salary of employee/staff of a certain university named XYZ University. Assume we have three employees in the university with ranks - Programmer, Admin and Librarian, write a Java program to calculate and printout the total salary of these three employees in the institution. The program should have the following features: 1) Create a public class named: Employee that would get the firstname and lastname of each employee from the keyboard/user 2) Create three objects: prog, adm and lib, for programmer, admin and librarian respectively to access the properties in Employee class. 3) Create EmployeeSalary as parent interface to store basic_sal, housing_all and transport_all. The values for these three items are fixed for all Employee and has abstract function calculateSalary. 4) Create three sub classes namely: programmer, admin and librarian to store bonus, overtime and total salary for each employee 5) Each of the constructor in (4) should inherit the properties of Employee(using the super keyword) and implement the EmployeeSalary interface. 6) Hide the properties from the parent class Employee using encapsulation principle. 7) Use getters and setters to make the properties in Em
OOPs
In today's technology-driven world, computer programming skills are in high demand. The object-oriented programming (OOP) approach is very much useful while designing and maintaining software programs. Object-oriented programming (OOP) is a basic programming paradigm that almost every developer has used at some stage in their career.
Constructor
The easiest way to think of a constructor in object-oriented programming (OOP) languages is:
