The document outlines a Java program that simulates an ATM machine utilizing an 'Account' class. The program allows for the creation of ten accounts with an initial balance of $100, and provides functionality for viewing balance, withdrawing, depositing, and exiting the menu based on user input. It includes detail about how the program validates user IDs and displays corresponding menus and actions until the user chooses to exit.

1. Java program
I made this Account.java below. Using the attached code I need help with 10.7 (Game: ATM
machine)
Use the Account class created in Programming Exercise 9.7 to simulate an ATM machine.
Create ten accounts in an array with id 0, 1, . . . , 9, and initial balance $100.
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. Thus, once the system starts, it will not
stop.
