PROGRAM TO GENERATE PAYSLIP USING INHERITANCE

AIM

To develop a java application to generate pay slip for different category of employees using the

concept of inheritance.

PROCEDURE

1. Create the class employee with name, Empid, address, mailid, mobileno as members.

2. Inherit the classes programmer, asstprofessor,associateprofessor and professor from employee

class.

3. Add Basic Pay (BP) as the member of all the inherited classes.

4. Calculate DA as 97% of BP, HRA as 10% of BP, PF as 12% of BP, Staff club fund as 0.1% of BP.

5. Calculate gross salary and net salary.

6. Generate payslip for all categories of employees.

7. Create the objects for the inherited classes and invoke the necessary methods to display the

Payslip.
