CMSC 203, Assignment 3



Concepts Utilized in this Project

• Javadoc
• UML diagrams
• Java classes and aggregation
• UI design & implementation, including widgets such as:
o Stage
o Scene
o Event programming
o Radio Buttons
o Check Boxes, Labels, Buttons

Overview

A small bank has recently hired you to design & implement an application which the bank will use to manage accounts and (account) transactions for its customers. A typical customer would be able to possess one or more checking, saving, money market, and/or certificate of deposit (CD) accounts with the bank. The customer would also be able to conduct typical banking transactions, such as:

• making deposits to their account
• withdrawing cash from their account
• obtaining account balances and such

Using Java, design and implement a GUI application for the bank to support its banking needs.

Specifications & Requirements
You will need the following classes:

Data Element – Customer class

Create a Customer class. It will contain instance variables of type String for the first name and last name. Provide constructors, getters and setters. Add any additional methods as required. Follow the Javadoc given you.
Data Element – BankAccount class

Create a BankAccount class that contains instance variables of a Customer and a double that holds the balance of the account. Provide constructors, getters and setters. You will need methods for deposit, withdraw and getting the account balance. Add any additional methods as required. Follow the Javadoc given you.

GUI driver – JavaFX

Include items such as labels, text boxes, buttons, dropdown lists, etc. Provide events/event handling for the following buttons:
• Create – extract the first name and last name from the text boxes, create a BankAccount object.
• Deposit – extract the amount from the text box, call the deposit method of the BankAccount class. Display the new balance by calling the method that returns the account balance.
• Withdraw - extract the amount from the text box, call the withdraw method of the BankAccount class. Display the new balance by calling the method that returns the account balance.
• Clear – clear the transaction amount text box
• Exit – exit the application

When starting the program, only firstname and lastname text boxes and create account button should be editable.



After you create the new account, the first and last name text boxes and the create account button become uneditable and the other buttons and text boxes become editable.


 
Enter the Transaction Amount


Select Deposit button


Select Clear button – clears the transaction amount text box





Deliverables / Submissions:

In addition to completing the Java application, Javadoc files and a write-up are required. Be sure to review the provided project rubric to understand project expectations. At a minimal, the write-up should include:
• Pseudo-code in English showing the steps to solve the problem
o It must be detailed enough for someone else to write the code based on this algorithm
o Complete this step first, and then write your code
• Test Cases
o Prepare a test table with a list of test cases (expected versus actual results) that you are testing the application with
o Same expectations as Assignment 1
• UML diagrams
• Any assumptions that you are making for this project
• In three or more paragraphs, highlights of your learning experience
• CheckList for Assignment 3

Each student must submit two compressed (.zip) files to the assignment’s folder on Blackboard for this project with the following contents:

• LastNameFirstName_Assignment3_Complete.zip, a compressed file in the zip format, with the following:
o Write up (Word document)
o Javadoc (directory)
 File1.html (example)
 File2.html (example)
o src (directory)
 File1.java (example)
 File2.java (example)
• LastNameFirstName_Assignment3_Moss.zip, a compressed file containing one or more Java files:
o File1.java (example)
o File2.java (example)
o This folder should contain Java source files only
