hello! can you help debug my Java program? here are the errors I am getting: line 67: id cannot be resolved to a variableline 102: id cannot be resolved to a variableline 110: id cannot be resolved to a variableline 119: id cannot be resolved to a variable should I re-initialize ID somewhere? is it not a public enough variable? thank you for any insight you can give.   here is my code: package automaticTellerMachine;   //header importing files import java.text.DecimalFormat; import java.util.Scanner;   //class Accountability class Account { public int id; public double balance; public Account() { //where the variables live id = 9; balance = 0; } public Account(int a, double b) { id = a; balance = b;   }   //defining the methods public double getBalance() { return balance; } //this is the depositing part public void deposit(double a) { //this is depositing at work balance = balance+a; } //this is the withdrawing part public void withdraw(double a) { //if you have enough $$$ if(a<=balance) { //this is the math part balance = balance-a; } //otherwise, error!!! else { //error in action! System.out.println("You do not have enough balance. Transaction ignored. Please try again.");   } } }   //new class: AutomaticMoneyMachine class AutomaticTellerMachine { //it's the main method! public static void main(String[] args) { //This is the Object of the Class Account[]account=new Account[10]; //terminate if i is greater or equal to 500 for (int i=0; i<500; i++) { //100 is a good starting amount account[id]=new Account(i, 100); } //loop while(true) { //this is the object for the Scanner class to pick up Scanner keyboard=new Scanner(System.in); System.out.println("Enter your account ID:"); int id=keyboard.nextInt(); //while loop repeats - ID must not be 0 and there are only 500 accounts, so while ((id>500)||(id<0)) { //hint for user about what went wrong System.out.println("Please try again. There are only 500 accounts at Longitude Banking. We are very exclusive."); id=keyboard.nextInt(); }} //while loop so that we can show the menu & the choices in it while(true) { //here is the scanner specifically for this menu Scanner sc=new Scanner(System.in);   //it is the menu! System.out.println("Welcome!!!"); System.out.println("1: Current balance"); System.out.println("2: Deposit"); System.out.println("3: Withdraw"); System.out.println("4: Exit");   //what value? Let me file that away via Scanner int choice=sc.nextInt(); //balance choice if(choice==1)   { System.out.println("You have $"+account[id].getBalance()+" in your account."); }   //deposit choice else if(choice==2) { System.out.println("Enter the amount you want to deposit: "); double deposit = sc.nextDouble(); account[id].deposit(deposit); System.out.println("You have deposited"+deposit+"into your account."); }   //withdrawing choice else if(choice==3) { System.out.print("Enter the amount you would like to withdraw: "); double withdraw=sc.nextDouble(); account[id].withdraw(withdraw); System.out.println("You have withdrawn"+withdraw+"from your account."); } //exit choice else if(choice==4) { //thank you message System.out.println("Successfully logged out. Thank you for banking with Longitude Banking."); //exit System.exit(0); } } } }
