Question

this is for java programming

Please use comments

Use the Account class created in homework 8_2 to simulate an ATM machine. Create ten checking accounts in an array with id 0, 1, …, 9, initial balance of $100, and annualInterestRate of 0. The system prompts the user to enter an id between 0 and 9, or 999 to exit the program. If the id is invalid (not an integer between 0 and 9), ask the user to enter a valid id. Once an id is accepted, display the main menu 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 for the selected account. Once you exit, the system will prompt for an id (of an account) again.

*** Please read sections 7.1 and 7.2 of Revel on the basics of single dimensional arrays if needed.

Game over. Good bye!

This is a test run but this a way the program needs to run, please try and keep it simple and nothing too complex if possible

Answer 1

Here is code:

import java.util.Scanner;

public class AtmAccount {

public static void main(String[] args) {
Scanner input = new Scanner(System.in);
int[] balance = { 100, 100, 100, 100, 100, 100, 100, 100, 100, 100 };
int choice = 0, id;
double amount;
System.out.println("Welcome to the ATM machine game!");
while (true) {
System.out.print("Enter an ID between 0 and 9, 999 to quit the game: ");
id = input.nextInt();
while ((id < 0 || id >= balance.length) && id != 999) {
System.out.print("Please Enter an ID between 0 and 9, 999 to quit the game: ");
id = input.nextInt();
}
if (id == 999)
break;
do {
System.out.println("\t\t1. = View your Balance");
System.out.println("\t\t2. = Withdraw Cash");
System.out.println("\t\t3. = Deposit Cash");
System.out.println("\t\t4. = Exit");
System.out.print("\nEnter your selection: ");
choice = input.nextInt();
if (choice < 1 || choice > 4) {
System.out.println("Invalid choice, Try again");
} else {
if (choice == 1) {
System.out.println("\nYour current balance is " + balance[id] + "\n");
} else if (choice == 2) {
System.out.print("\nEnter the amount your want to withdraw : ");
amount = input.nextDouble();
balance[id] -= amount;
} else if (choice == 3) {
System.out.print("\nEnter the amount your want to deposit : ");
amount = input.nextDouble();
balance[id] += amount;
} else if (choice == 4) {
break;
}
}

} while (choice != 4);
}

}

}
