Question

Java program that acts like an ATM: Using class call "Account" simulate an ATM machine. Create ten accounts in an array with ID 0, 1 ... 9. and with an initial balance of $100. The system prompts the user to enter and ID. If the ID is entered incorrectly, ask the user to enter the correct ID. Once the ID is accepted the main menu is displayed as shown below. Choice 1 = View current balance. Choice 2 = Withdraw Money. Choice 3 = Deposit Money. Choice 4 = Exit the Main Menu. Once you exit, the system will prompt you for your ID again. So once the system starts, it will not stop. This is a introduction to Java class. No GUI needed. All is by command line. Thanks! Enter an ID: 4 [Enter] Main Menu 1: Check Balance 2: Withdraw 3: Deposit 4: Exit Enter a choice: 1 [Enter] The balance is 100.0
