1. Overview As a team, you are to complete several enhancements the Banking Application we went over in class: Add a new account type: Certificate of Deposit Add a List All function to the main menu Be sure to use inheritance to create the new account type and to make the Listing function very general. 2. Problem Description New Account Type Our client, ACME bank, will be offering a new Account Type: the Certificate of Deposit, also known simply as a CD. This new account behaves like any other Bank Account with the following exceptions: On creation: We must provide an interest rate, a term in months and an initial balance. Keep track of the number of months remaining until maturity (the term). Withdrawals before the term is up result in a penalty. On month end: Add interest to the account (rate x current balance). Reduce the number of remaining months in the term (but not to below 0). On withdrawal: Regardless of how much the account holder attempts to withdraw, a CD is an all-or-nothing account. Any attempt to take out money withdraws it all. If the account owner withdraws money before the CD matures, assess a 10% penalty. Print a message like this: Early CD Withdrawal. $1075.00 penalty, $9675.00 cashed out If the money is withdrawn after the CD matures, there is no penalty. Print a message like this: Mature CD Withdrawal. No penalty, $5512.50 cashed out Name the new class: CDAccount. New Application Functionality Our client would also like a nice list of all the active accounts. Add a new option to the User Menu: List All which is selected with an 'L'. When selected, the system will print details of each account. The information printed will be specific to each Account type. You are to do this by overriding and using the Object.toString() method. Output examples appear below: 0: Checking: Balance=$100.00, Allowed Withdrawals=3, #Withdrawals=0 1: Savings: Balance=$200.00, Minimum=$100.00, Rate=0.025% 2: CD: Balance=$10000.00, Term=60, Rate=0.075% Month end still prints short list as it always has.
