please look at extra credit and notes. must be sent to file, please

it is the database that has the account numbers and balances. I am not sure. the second paragraph says "the account information of existing customers is to be read in to a pair of parallel arrays". Would that have anything to do with it? i am sorry, not sure. please help

You have been hired as a programmer by a major bank. Your first project is a small banking transaction system. Each account consists of a number and a balance. The user of the program (the teller) can create a new account, as well as perform deposits withdrawals, and balance inquiries Initially, the account information of existing customers is to be read into a pair of parallel array-one for account numbers, the other for balances. The bank can handle up to MAX NUM accounts. Use the following method to read in the data values public static int readacets (intl acetNum, double balance, int maxhcets) This method fills up the account number and balance arrays (up to maxActs) and returns the actual number of counts readin Cater referred to as mums ts After initialization, the main program prints the initial database of accounts and balances. Use method prin described below The program then allows the user to select from the following menu of transactions Select one of the following: W. Withdrawal D. Deposit N New account B. Balance Q- Quit X-Delete Account - Extra Credit Use the following method to produce the menu: public static void menu () This method only displays the menu. The main program then prompts the user for a selection. You should verify that the user has typed in a valid selection (otherwise print out an error message and repeat the prompt). Once the user has entered a selection, one of the following methods should be called to perform the specific transaction. At the end, before the user quits, the program prints the final contents of the account and balance arrays public static int findAcct (int[] acetNum, int numAccts, int account); This method returns the index of account in the actNum array if the account exists, and 1 if it doesn't. It is called by all the remaining methods. public static void withdrawal (int) acetNum, double balance, int numActs); This method prompts the user for the account number. If the account does not exist, it prints an error message. Otherwise, it asks the user for the amount of the withdrawal. If the account does not containsufficient funds, itprints an error message and does not perform the transaction pubic static void deposit(int il acctum, doublell balance, int num_accts); This method prompts the user for the account number. If the account does not exist, it prints an error message. Otherwise, it asks the user for the amount of the deposit public static int newAcetint Il acctum, double balance, int nucets) This method prompts the user for a new account number. If the account already exists, it prints an error message. Otherwise, it is the account to the acct Numaray with an initial balance of returns the new number of accounts public static void balance (int[] acet , doublell balance, int numits); This method prompts the user for an account number. If the account does not exist, it prints an error message. Otherwise, it prints the account balance public static void printacets (intl acetNum, doublell balance, int nuts); This method prints a 3-column table of all customer information-account numbers and balances EXTRA CREDIT 1: public static int deleteAcct (int[] acct Num, double[] balance, int numAccts); This method prompts the user for an account number. If the account does not exist, it prints an error message. Otherwise, it deletes the account. It returns the new number of accounts. EXTRA CREDIT 2: public static int deleteAcct (int[] acct Num, double[] balance, int numAccts); This method prompts the user for an account number. If the account does not exist, or if the account exists but has a non-zero balance, it prints an error message. Otherwise, it deletes the account. It returns the new number of accounts Notes: 1. All output must be file directed (you must add additional parameters to the methods as needed) 2. Only output must go to the file - not interactive prompts or menus (which go to the monitor). 3. No global variables are allowed 4. The program and all methods must be properly commented. 5. The program must be properly tested. a. The initial database should consist of at least 7 accounts b. The initial database should be printed to the file c. Test at least 2 invalid menu selections d. Test at least 2 balance inquiries: i. valid account i invalid account e. Test at least 3 deposits: i. valid account - valid deposit amount ii. valid account - invalid deposit amount Hii invalid account f. Test at least 4 withdrawals: i. valid account - valid withdrawal amount ii. valid account - invalid withdrawal amount ill. valid account - insufficient funds iv. invalid account 2. Create at least 3 new accounts with an initial balance of 0.0 h, Test the creation of at least 1 invalid new account i. Test several transactions on the new accounts (deposits, withdrawals, etc.) j. Extra Credit: Delete at least two accounts (both must be old accounts that had no transactions) State whether you are doing Extra Credit 1 or Extra Credit 2 Extra Credit 1 is worth +1: Extra Credit 2 Is worth +2 k. quit and print the final database Sample Output: Transaction Type: Deposit Account Number: 9876 Current Balance: $300.50 Amount to Deposit: $123.45 New Balance: $423.95 Transaction Type: Withdrawal Account Number: 9876 Current Balance: $423.95 Amount to withdraw: $765.43 Error: Insufficient Funds Available
