Bank Teller

Objective

Design a banking application that handles standard interaction that a user would have with their bank.

• Design a Account class that will handle instances of a bank account.
• Design a Bank class that will house multiple accounts the user may have.
• Design a BankApplication (with a main method) to build a user interface where your user can access their accounts and perform standard transactions.

Tasks

The Account Class should have:

• 3 instance variables to handle String accountNumber, String accountType, and double accountBalance (Note the accountNumber will be a unique identifier)
• Create a constructor that accepts input for your three instance variables
• Create accessor methods for each instance variable in Account
• Create a deposit method for adding funds
• Create a withdrawal method for retrieving funds.
• Create a checkAccountBalance method to show available funds

The Bank Class should have:

• A Map called accounts
• A getAllAccounts() method to return a Collection<Account> containing all accounts
• An openNewAccount() to add an Account to accounts
• A getAccount(String accountNumber) to get access a particular Account
• A closeAccount(String accountNumber) to close a particular Account

Hint: This Class operates like a bank and keeps track of multiple bank accounts.

The BankingApp should have:

• A Bank object
• Two unique Account objects properly instantiated
• Add your Accounts to your Bank objects Map
• Set up a UI to give the user the ability to interact with the application:
  • Display Accounts and their info.
  • Display a menu to give your users choices to:
    • Make a deposit to an Account
    • Make a withdrawal from an Account
    • Check the balance on an Account
    • Close an Account
    • Exit the application
  • Accept input from the users choice and display the appropriate response
  • Include a loop so the user can continue to manipulate accounts

Stretch Task #1: Include a security system that requires the user to enter a correct PIN (Personal Identification Number) before they can access the application. (Think about the most appropriate place to house this information)

Stretch Task #2: Refuse to close an account that still has remaining funds. Let the user know they can't remove an account that has funds remaining and prompt them to make another choice.
