CS8382-OBJECT ORIENTED PROGRAMMING LABORATORY-JAVA EMPLOYEE PROGRAM USING INHERITANCE CONCEPT FOR

CS8382-OBJECT ORIENTED PROGRAMMING LABORATORY

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.
