Array of Objects Use the Account class created in Question 5 of Assignment 2 to simulate an ATM machine (name the class as ATMWithAccount). Create ten accounts in an array with id 1, 2, ..., 10, and initial balance $100. The array index for each account is the same as the account id. (Hint: This indicates that the array size is 11.) Set the first array element as null. The system prompts the user to enter an id. If the id is entered incorrectly, ask the user to enter a correct id. Once an id is accepted, the main menu is displayed as shown in the sample run. You can enter a choice 1 for viewing the current balance, 2 for withdrawing money, 3 for depositing money, and 4 for exiting the main menu. Once you exit, the system will prompt for an id again. Once you enter id 0, the program prints out a summary of the ten accounts, including the id and the balance. Then the program is terminated. All floating-point numbers should be printed out with 2 decimal places. A sample run is as follows: Enter an account id (1-10): 11 Invalid id Enter an account id (1-10): 4 Main menu 1: check balance 2: withdraw 3: deposit 4: exit Enter a choice: 1 The balance is 100.00 Main menu 1: check balance 2: withdraw 3: deposit 4: exit Enter a choice: 4 You exit this account Enter an account id (1-10): 5 Main menu 1: check balance 2: withdraw 3: deposit 4: exit Enter a choice: 2 Enter an amount to withdraw: 200 Your balance is not enough.

Array of Objects

Use the Account class created in Question 5 of Assignment 2 to simulate an ATM machine (name the
class as ATMWithAccount). Create ten accounts in an array with id 1, 2,
10, and initial balance
$100. The array index for each account is the same as the account id. (Hint: This indicates that the array
size is 11.) Set the first array element as null. The system prompts the user to enter an id. If the id is
entered incorrectly, ask the user to enter a correct id. Once an id is accepted, the main menu is displayed
as shown in the sample run. You can enter a choice 1 for viewing the current balance, 2 for withdrawing
money, 3 for depositing money, and 4 for exiting the main menu. Once you exit, the system will prompt
for an id again. Once you enter id 0, the program prints out a summary of the ten accounts, including
the id and the balance. Then the program is terminated. All floating-point numbers should be printed out
with 2 decimal places. A sample run is as follows:
Enter an account id (1-10): 11
Invalid id
