Java program to create payslip for employees by using Inheritance

/*QUESTION:

Develop a java application with Employee class with Emp_name, Emp_id, Address,

Mail_id, Mobile_no as members. Inherit the classes, Programmer, Assistant

Professor, Associate Professor and Professor from employee class. Add Basic Pay

(BP) as the member of all the inherited classes with 97% of BP as DA, 10 % of BP

as HRA, 12% of BP as PF, 0.1% of BP for staff club fund. Generate pay slips for the

employees with their gross and net salary*/
