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 Employee visible and accessible to other
classes: programmer, admin and
librarian.
8) The total salary should be computed by adding basic salary, housing allowance, transport
allowance, and bonus, overtime.
9) The printout of the program should display the following for each employee: firstname and
lastname, basic salary, housing allowance, Transport allowance, bonus, overtime and total
salary.
SAMPLE OUTPUT WOULD BE:
run:
EMPLOYEE #1:
Enter a First Name: Steven
Enter a Last Name: Pato
Programmer’s Firstname and LastName are:Steven Pato
Programmer’s Basic salary is:40000.0
Programmers Housing Allowance is:20000.0
Programmers Transport Allowance is:7000.0
Bonus of Programmer is:12000.0
overtime of Programmer is:9100.0
TOTAL SALARY OF PROGRAMMER IS:88100.0
EMPLOYEE #2:
Enter a First Name: Grace
Enter a Last Name: Tioni
Programmer’s Firstname and LastName are:Grace Tioni
