Question

hello! can you help debug my Java program?

here are the errors I am getting:

line 67: id cannot be resolved to a variable
line 102: id cannot be resolved to a variable
line 110: id cannot be resolved to a variable
line 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);

}
