Requirements:
Consider the three Java Classes: Borrow, RepayCalc and RepayCalcMenu, available from the
Assignment 2 page on Vista.

You are required to perform the following tasks:

The RepayCalcMenu class: (Total maximum 20 marks available)

   1. Provide a basic text-based interface to a Repayment Calculator for the Megalodon
         Finance Company so that it can be used by the Megalodon staff members to
         determine repayment options for their clients.

         The staff must be able to:

         * Log on to the ‘system’ using their user name and a Personal Identification
            Number (PIN), which a four digit number **.

               * The user should not be able to use the ‘system’ until they have provided the
                     correct user name and PIN combination. You should give them a second or
                     third chance to get it right before shutting the ‘system’ down.



            ** You must use the user names and passwords provided in your individual

            data available from the Assignment 2 page on Vista (see requirement 5 below).
            The user names and passwords should be included in your code, and the output
            to the screen should prompt the user with the user names and passwords (for

            marking purposes).



* The interface should provide a menu so that the staff can:

            - Perform a Repayment calculation

            - Print out to the screen the Repayment details

            -    Change one, two, or all of the values for the current calculation

            -    Start a new calculation

            - Leave the program.
The RepayCalc class: (Total maximum 10 marks available)

   2. Provide a method to accept three input values from the user:

            -    the Amount to be Borrowed (to 2 decimal places, for example, 10550.00)

            -    the Annual Interest Rate (to 2 decimal places, for example, 9.75)

            -    the Period of Repayment (in whole Years, that is, no fractions of a year)

   3. Provide a method to print out to the screen the three input values (accepted in
         requirement 2), plus the repayment calculations:

            -    the Weekly repayments

            -    the Total repayment amount (Amount borrowed + Interest)



The Borrow class: (Total maximum 40 marks available)

   4. Provide methods to perform the following tasks:

            -    to calculate the weekly repayments ***

            -    to calculate the total repayment amount

            -    to return the amount borrowed

            -    to return the borrowing period in years

            -    to return the borrowing period in weeks

            -    to return the annual interest rate

            -    to return the weekly repayments

            -    to return the total repayment amount

            -    to reset the loan amount

            -    to reset the annual interest rate

            -    to reset the loan period (in years)





            *** Use a simple interest calculation (not compound) formula, for example:

         weeklyRepayment = (borrowedAmount * 1 + (annualInterestRate *
         numberOfYears )) / numberOfPayments;





Individual Data (Maximum 10 marks available)

   5. You will be given two Megalodon staff member user names and passwords, plus a set
         of data for each staff member to use to calculate repayment details. You will need to
         log onto the BSA104 Assignment 2 page on Vista to generate your individual data
         and instructions for this requirement. You will need to use your University of
         Tasmania (UTas) student number.


                                                      Page 2 of 5

For requirement 5 use the following data:

# Data Set 1:

User name: JordanM
Password:  Ferrari
Borrowed: $ 749.95
Interest: 15.0 %
Years:    4

# Data Set 2:
