Question

Q. No. 02 Consider the following class Certification with following data members Id (int), name (String) , hours(int), level (String), costPerHr (double) Implementation of this class is provided on moellim. You are required to do the following  Provide a class StudentCertification that extends Certification . This class has an additional data member rebate (double) o Override the calculateFee method so that the total cost is calculated by getting the total for the training hours @costPerHr and applying the rebate (%). E.g. if the costPerHr is 200 and 50 hours training and 0.2 rebate then the calculateFee should return 10000 – 0.2 *10000 = 8000 
