PROJECT

Requirement – COSC2426_FA2018_BANK SERVICE APPLICATION

A bank asks for an application for their bank service. That can help bank employees and bank

customers to do some tasks relating to their bank service.

The application should keep the information of Bank Customer including customer id (String

or a number), lastname(String), firstname(String), user name(String), password(String),

address (String) and a list of accounts that keeps all bank accounts (java LinkedList)

Besides the constructors, the class of Bank Customer should have some methods that relates

to some actions of a bank customer, for example, open one new account, close one account,

read one account, method to write information of customer to an output file, method to print

the bank customer information that lists customer’s name, id, address, and the list of all

accounts in the following format (for example):

Liem Le | COSC2436 #3

Beside Bank Customers, the application needs to manage Bank Accounts that need:

-Class BankAccount has account number (String) and balance (float)

-Class BankCheckingAccount inherits account number(String) and balance (float) from class

BankAccount and also have limitAmount (float) that is smallest amount of money in the

account and serviceFee(float)

-Class BankSavingAccount inherits account number (String and balance (float) from class

BankACcount and also have limitAmount (float) and interestRate(float)

-These classes should have constructors, method check balance, deposit, withdraw, print

monthly statement, toString and method write to file

Each Bank Customer has several accounts; either Checking account or Saving account.

Therefore, in the class Bank Customer, you can use java LinkedList as a data member to hold

all account that customer has

The project will keep BankCustomer as nodes and place them to a data structure type when

the project starts. You can select any type of data structure that we learned from the course

(UnsortedOptimizedArray, Singly LinkedList, Hashed, OR Tree) ➔ Therefore, you should

provide the class of the selected data structure

TOTAL YOU HAVE at least 6 CLASSES INCLUDING THE DRIVER CLASS: class of

BankCustomer_yourLastName, Account_yourLastName, CheckingAccount_yourLastName,

SavingAccount_yourLastName, class of data structure type and the driver class named

BankService_yourLastName

Suppose that the Bank stores all the information of Bank Customers in an Excel file

bankCustomers.xlsx (downloaded from eCampus)

Before running the program, you have to open the file bankCustomers.xlsx then Save As with

the extension is csv ➔ bankCustomers.csv

(Note: When you read the file with the extension .csv the information of all cells in each row

will be separated by comma “,”

For example:

222,Smith,James,bbb,bbb,djkf dkjfdjkfd,1850191232,2000.0,20.0,10.0,1389701422,500.0,100.0,.0005,

Liem Le | COSC2436 #4

The Bank Service application is for the bank emploees and the bank customers

1. FIRST, OPEN INPUT FILEE (bankCustomer.csv) READ EACH LINE INCLUDING INFORMATION OF ONE CUSTOMER, SPLIT INFORMATION THEN CREATE A NODE OF BankCustomer AND INSERT THE NODE TO DATA STRUCTURE

AFTER READ ALL LINES TO INSERET TO DATA STRUCTURE, USE SHOW ALL TO SHOW ALL

NODES FROM DATA STRUCTURE BEFORE CONTINUE DISPLAY THE MAIIN MENJU

2. PROVIDE THE MAIN MENU

Display the main menu to allow users select the user type:

COSC2436 FA2018 BANK SERVICE APPLICATION

1. Bank Employee 2. Bank Customer 0. Exit

When users select 0 for exit: OPEN THE OUTPUT FILE WITH THE SAME NAME AS ABOVE INPUT

FILE (bankCustomer.csv) TO WRITE:

FOR EACH NODE OF A CUSTOMER IN THE DATA STRUCTURE, COMBINE THE INFORMATION OF

THE CUSTOMER TO ONE LINE THEN WRITE THE OUTPUT FILE IN THE SAME FORMAT WHEN

YOU READ AT THE BEGINNING FOR NEXT USE

(see the file bankCustomer.xlsx for the format of one line)

When users select 1 for Bank Employee, display the following menu:

TASKS FOR BANK EMPLOYEES

1. Add a New Customer – Open New Account 2. Display a Customer With All Accounts 3. Open New Account for Current Customer 4. Read One Account of One Customer 5. Remove One Account of Current Customer 6. Display all Customers with their accounts 7. Process Monthly Statement 0. DONE

When employees select 0 for DONE, re-display the main menu.

When users select 2 for Bank Customers, display the follow menu:

TASKS FOR BANK CUSTOMERS

1. Print Information of Customer 2. Check balance 3. Deposit 4. Withdraw 5. Print Monthly Statement 0. DONE

When users select 0 for DONE, you will re-display the main menu

Liem Le | COSC2436 #5

TASK FOR BANK EMPLOYEES:

TASK 1: Add a New Customer – Open New Account

-display message to ask for information to create a new customer with at least one account

opening. The account number should be generated randomly and check to ensure it is unique

in the system.

(Note: You can use a LinkedList to keep all account numbers. Every new account number

should be compare to all existing account number in this linked list. If the new account

number is the same an existing number, the program should generate different one.)

-insert the new customer to the data structure

TASK 2: Display a Customer With All Accounts

-Ask for customer id, then look for the customer in data structure.

-if cannot find the customer with the id, display the message: “Customer cannot be found”

-if the customer is found, display all the information of one Customer as below (using the

object to call the method to print all information and list of accounts from class

BankCustomer)

TASK 3: Read One Account of One Customer

-ask for how to login:

SELECT LOGIN TYPE

1.Customer id

2.User name and password

0.DO NOT CONTINUE

If user select customer id, ask and read customer id

If user select user name and password, ask and read username and password

-Using “id” or “username + password” to read (fetch) a customer from data structure (You

should provide two fetch methods, one fetch by id and one fetch by username+password)

-Ask and read the account number that users want to read

-Using a method in class BankCustomer to search for the account with the account number

-If account cannot be found, display message

-If account is found, display account information, by using toString

OR

Liem Le | COSC2436 #6

TASK 4: Open New Account for Current Customer

-ask for customer Id to find the correct customer from the data structure

-ask for account type and all information enough to create one account either Checking

account or Saving account

-create account (remember to apply polymorphism)

-add the new account to the list of account of this customer by call the method

addNewAccount of class BankCustomer to add an account to list of account

-display the message to verify add account complete

For example:

Open new Account for Customer with id: 7654321 SUCCESS

TASK 5: Remove One Account of Current Customer

-ask for customer id to find the correct customer from data structure

If the customer cannot be found, display message: “The customer with <id> does not exist”

If the customer is found:

-ask for account number that users want to delete

-if account cannot be found, display the message

-If account is found:

* if this customer only have one account and he want to close, display the message to let users

confirm:

This customer only have one account

Close this account will remove this customer off the system

Do you still want to close account (Y/N)?"

If he says N, do not close the account

If he says Y,

* remove the account by calling the method closeAccount of class BankCustomer

* remove account number from the list of account number

* Delete this customer from data structure

TASK 6: Display all Customers with their accounts

-show all the customer in the data structure, call the method showAll from data structure

TASK 7: Process Monthly Statement

-generate monthly statements of each account of all customer by calling the method process

the monthly statement from the class data structure
