Consider following class Certification with following data members Id (int), name (String) ,hours(int),level (String),costPerHr (double). Provide a class StudentCertification that extends Certification. This class has an additional data member rebate (double). 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. Provide another sub class ProfessionalCertification that extends Certification. This class no additional data member. It overrides calculateFee method so that total cost is returned as product of hours and cost per hour plus 15% tax of total hours cost. Also ProfessionalCertification implements Extendible Interface. You will also have to provide the implementation of method extend(int duration). For this you need to add the duration to training hours of the certification  

Write a method called sumFirstAndLastDigist() with one parameter of type int called number.

.

The methods needs to find the first and Last digist of the parameter number passed to the method, using a loop and return the sum of the first and Last digis

.

Here's an example:

Let's say you call sumFirstAndLastDigit(23456);

This should return 8 because 2 + 6 = 8

You are required to build an application for charity organization. Your application will keep track of the items given out as charity. The items are donated by people and your application will keep track of each donation in persistence store. CharityItem: description (String), quantity (int), estimatedAmount (double), donor name (String), Donor contact (String) You are also required to do some exception programming/handling. If a charity with a value greater than 2 lacs is donated, then you will raise the ShowOffCharityException. You will have to create an exception class for this and the exception will be raised from the constructor of the CharityItem class under the said condition. You will also write code at other places wherever required to deal with this exception. Please note that you will make your ShowOffCharityException as a checked exception. 

Provide another sub class ProfessionalCertification that extends Certification. This class no additional data member. o It overrides the calculateFee method so that the total cost is returned as the product of hours and cost per hour plus 15% tax of the total hours cost. o Also the ProfessionalCertification implements the Extendible Interface. You will also have to provide the implementation of method extend(int duration). For this you need to add the duration to the training hours of the certification  The correctness of your code will be checked against a main program that will be provided along with the expected output
