Home/Engineering & CS/I need(1. The Java source code file (e.g., HW7_1.java) 2. The initial database of accounts file (initAccts.txt) 3. The test cases input file (e.g., testCases.txt) 4. The program generated output file (e.g., output.txt) 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 ii. invalid account e. Test at least 3 deposits: i. valid account - valid deposit amount ii. valid account - invalid deposit amount iii. invalid account f. Test at least 4 withdrawals: i. valid account - valid withdrawal amount ii. valid account - invalid withdrawal amount iii. valid account - insufficient funds iv. invalid account g. 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.) 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 arrays--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 readAccts(int[] acctNum, double[] balance, int maxAccts) This method fills up the account number and balance arrays (up to maxAcets) by reading from an input file until EOF is reached, and counting how many accounts are read in. It returns the actual number of accounts read in (later referred to as numAccts). After initialization, the main program prints the initial database of accounts and balances. Use method printAccts() 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 acctNum 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 numAccts); 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 contain sufficient funds, it prints an error message and does not perform the transaction. pubic static void deposit(int[] acctNum, double[] 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 newAcct (int[] acctNum, double[] balance, int numAccts); This method prompts the user for a new account number. If the account already exists, it prints an error message. Otherwise, it adds the account to the acctNum array with an initial balance of O. It returns the new number of accounts. public static void balance (int[] acetNum, 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 prints the account balance. public static void printAccts (int[] acetNum, double[] balance, int numAccts); This method prints a 2-column table (with column headings) of all customer information--account numbers and balances. 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

8. A billiard ball (mass m = 0.150 kg) is attached to a light string that is 0.50 meters long and swung so that it travels in a horizontal, circular path of radius 0.40 m, as shown. 0.50 m a. On the diagram, draw a free-body diagram of the forces acting on the billiard ball. b. Calculate the force of tension in the string as the ball swings in a horizontal circle. c. Determine the magnitude of the centripetal acceleration of the ball as it travels in the horizontal circle. d. Calculate the period T (time for one revolution) of the ball's motion.
Problem 8: Find the modeling equation(s) for the system shown below. Given, x=y=0 @ t=0 when all the three springs are undeformed. At the given instant, both springs (the spring attached to mass m2 and mass mi (stiffness 28)) are in tension and y> x. Note: The horizontal-spring (stiffness k) has its one end attached to mass mi and the other end to a fixed support (hinge). Hint: To model the spring forces due to the two springs that passes over the pulley: - you may assume them to be in series as long as the pulley is ideal (massless and frictionless). Replace the two springs by a single spring (having stiffness kog) between two displacements x and y Ideal Pulley 2k 000 000 m CO01 000 111
