Bank Account HELP!!!! PLEASE.

Okay, so basically I am an idiot and this is my first programming class. I am completely stuck on this program and I have been staring and messing with it for 4 days and cannot get it too work. For some reason I cannot get the variable to return. Someone please help, I am desperate.

Code :

import javax.swing.*;
 
public class Program4
{
    // Class Variables.
    public static String firstName = "";
    public static String lastName = "";
    public static double dollars = 0.0;
 
    public static boolean isOpened = false;
    public static boolean isOverdrawn = false;
 
    // Replace "CIS Faculty" with your name.
    private final static String TITLE_BAR = "Program 4 (Me)";
 
    // Class Methods
    // Add your methods below here.
    // You should leave the main method below ALONE!!
    public static void main(String[] args)
    {
 
        showAccount(); // Will show error message about account not open
        // and will then continue.
 
        // Open new account. Give error message if it fails!
        if (!openAccount("Bill", "Smith", 100.50))
        {
            reportErrorAndBomb("Coding error 1. Open account failed on a new account!");
        }
        showAccount();
 
        // Check that accountOwner works correctly - bomb if not.
        if (!accountOwner().equals("Bill Smith"))
        {
            reportErrorAndBomb("Coding error 2. Call to accountOwner failed.");
        }
        if (balance() != 100.50) // Verify balance is correct!
        {
            reportErrorAndBomb("Coding error 3. Balance is wrong!");
        }
 
        // Confirm that I cannot reopen it!
        if (openAccount("Bogus", "Try", 55.00))
        {
            reportErrorAndBomb("Coding error 4. You allowed an account "
                    + "to be re-opened!");
        }
 
        deposit(50.00);
        showAccount();

        }

        }

Re: Bank Account HELP!!!! PLEASE.

Sorry, like I said I'm new and dumb. I can't get the program passed the openAccount method. It hangs up and will not return the two strings and double. I have messed with it for days.

Code :

Re: Bank Account HELP!!!! PLEASE.

There is much wrong with this code from what I can see, use an IDE, such as eclipse or netbeans.
