Banking Application

Hello to all,
I am new to this forum and I will consider everything as an advice.
I need to develop a GUI application for a small bank which is going to hold Users, Accounts --> Different types, Visas, Checkings , Savings , Loans etc.
I have also a GUI called trasnactions...

I have started creating the GUIs using Netbeans , and the classes.
I will make the accounts interface so i will implement the Visas etc.
I dont know how to associate transactions with a class.


I dont know how to proceed.
I need to authenticate users using an interface and also i need a master driverr class to create users

:(

Any help is much appreciated...

Uhm.

Did you get some code to get you started? Because you could probably do this in alot of ways.
And what do you mean with "Users, Accounts --> Different types, Visas, Checkings , Savings , Loans etc"

That there is a Account classe? who has different types(methods) Visas,Checkings etc.
Or do you mean there there are different Acount classes : Visas Checkings etc.?

I have created the interface accounts and I will inherit and reimplelemnt the behavior in each of the accounts I mention.

Sample code below.
Please help :(

/* Accounts interface*/
interface Accounts
{
//to do here
}

/*End Accounts interface*/
/************************************************** ****************************/
/*Users Class*/
class Users
{
//Variables
private String userName;
private int userId;
private String userAddress;
private String userEmail;
private double userAccountBalance;
private double userTotalWithdrawals;
private double userTotalDeposits;

Users users=new Users();
ArrayList<Users> UsersList=new ArrayList<Users>(150);//allocate space for 150 Users in our Arraylist
//to do here methods to be specified
//methods below this line
}

/*End Users Class*/
/************************************************** ****************************/
/*Class Savings*/
class Savings implements Accounts
{
//to do here
}

/*End Savings Class*/
/************************************************** ****************************/
/*Class Checking*/

class Checking implements Accounts
{
//to do here
}

/*End Checking Class*/
/************************************************** ****************************/
/*Class Credit Cards*/
class CreditCards implements Accounts
{
//to do here
}
