I need assistance with an ATM program in Java. The criteria is below:
Create a program that subtracts a withdrawal from a Savings Account, and returns the following on the screen:
• username and password (input by user)
• Balance use any amount hard-coded in your code.
• Calculate interest at 1% of the Starting Balance
• Amount withdrawn (input by user)
• Amount Deposit (input from user)
• Interest Accrued (It is whatever equation you come up with from the starting Balance.)
• Exit (Exit out of the program
If the withdrawal amount is greater than the Starting balance, a message appears stating:
• Insufficient Funds- It should display a message "Insufficient funds" Next you will then ask the user to either exit or go back to the main menu.
• If the withdrawal amount is a negative number, a message should appear stating: Negative entries are not allowed. Thereafter you will then ask the user to either exit or go back to the main menu.
I need help with the following:
- If the withdrawal amount is a negative number, a message should appear stating: Negative entries are not allowed. Thereafter you will then ask the user to either exit or go back to the main menu.
- the username and password, how to loop it for them not to continue if the criteria is wrong.
This is what I have so far:
package project1package;
import java.util.;
public class ATM {
public static void main(String[] args) {
// TODO Auto-generated method stub
System.out.println("+----------------------------------+");
System.out.println("| Final Project |");
System.out.println("| ATM Machine |");
System.out.println("+----------------------------------+");
System.out.println("");
//Enter Username and Password
String username, password;
Scanner sc = new Scanner(System.in);
System.out.println("Enter your username in the following format (first intial.lastname): ") ;
username = sc.nextLine();
System.out.print("Intial Login password is 'Password!'. Enter your password: ") ; //password:user
password = sc.nextLine();
if(username.equals("username") || password.equals("Password!"))
{
System.out.println("Authentication Successful");
}
else
{
System.out.println("Authentication Failed");
}
System.out.println("Username: " + username);
System.out.println("Password: " + password);
//Intial Balance
int balance = 50000, withdraw, deposit;
double interest = balance .01;
//Display Balance
System.out.println("");
System.out.println("Balance: " + (balance + interest));
System.out.println("");
//create ATM functions
while(true)
{
System.out.println("Automated Teller Machine");
System.out.println("Choose 1 for Withdraw");
System.out.println("Choose 2 for Deposit");
System.out.println("Choose 3 for Check Balance");
System.out.println("Choose 4 for EXIT");
System.out.print("Choose the operation you want to perform:");
//get choice from user
int choice = sc.nextInt();
switch(choice)
{
case 1:
System.out.print("Enter money to be withdrawn:");
//get the withdrawl money from user
withdraw = sc.nextInt();
//check whether the balance is greater than or equal to the withdrawal amount
if(balance >= withdraw)
{
//remove the withdrawl amount from the total balance
balance = balance - withdraw;
System.out.println("Please collect your money");
}
else
{
//show custom error message
System.out.println("Insufficient Funds");
}
System.out.println("");
break;
case 2:
System.out.print("Enter money to be deposited:");
//get deposite amount from te user
deposit = sc.nextInt();
//add the deposit amount to the total balanace
balance = balance + deposit;
System.out.println("Your Money has been successfully depsited");
System.out.println("");
break;
case 3:
//displaying the total balance of the user
System.out.println("Balance : "+balance);
System.out.println("");
break;
case 4:
//exit from the menu
System.out.println("");
System.out.println("Enjoy your day!");
System.exit(0);
}
}
}

The purpose of the provided ATM program is to allow users to perform banking operations such as withdrawals, deposits, and balance checks. To handle negative withdrawal amounts, the code can include a condition to display an appropriate error message and prompt the user to retry.What is the purpose of the provided ATM program in Java and how can the code be improved to handle negative withdrawal amounts?The provided code is an ATM program in Java that allows users to perform various operations such as withdrawing money, depositing money, checking the balance, and exiting the program. It includes features like authentication using a username and password, displaying the initial balance with 1% interest accrued, and handling insufficient funds scenarios.To address the mentioned requirements:1. To handle negative withdrawal amounts, you can add a condition before processing the withdrawal in the `case 1` block. If the withdraw amount is negative, display a message stating that negative entries are not allowed, and ask the user to either exit or go back to the main menu.To implement the username and password verification: Create a loop that continues until the correct username and password are entered. Within the loop, prompt the user for the username and password, and compare them to the expected values. If the authentication is successful, break out of the loop and proceed with the rest of the program. If the authentication fails, display an appropriate message and continue the loop to prompt for credentials again.By incorporating these additions, the code will provide the desired functionality.Learn more about ATM programbrainly.com/question/14200620#SPJ11
