Question

Using Repl.it

In this assignment you will create a Java program that allows a Bank customer to do the following:

1) Create a bank account by supplying a user id and password

.2) Login using their id and password

3) Quit the program.

Now if login was successful the user will be able to do the following:

1) Withdraw money.

2) Deposit money.

3) Request balance.

4) Quit the program.

If login was not successful (for example the id or password did not match) then the user will be taken back to the introduction menu.

This is what your program in action will look like:

Hello

Welcome to Genesis Bank ATM Machine

Please select an option from the menu below:

l -> Login

c -> Create New Account

q -> Quit

> L

Please enter your user id: 12

Please enter your password: 2345

Create an Array List of about 10 Bank customers, basic money transactions for deposit, withdrawal, and balance checking.
