Problem Statement
CIS355 Lab 5 – Portfolio Management GUI and File IO
CIS355A Week 5 Lab

CIS355A Week 5 Lab—File Processing

OBJECTIVES
• Add persistent data storage to your Week 4 Lab using text file input/output.

PROBLEM: Stocks4U Portfolio Management System
The portfolio management system you developed for Stocks4U needs the ability to save and restore a user’s data from a text file.

FUNCTIONAL REQUIREMENTS
You can code the GUI by hand or use NetBeans GUI Builder Interface.
You will enhance Week 4 GUI to include
• a File menu with menu items: open, save, exit; and
• a label to display total portfolio value.

Stock class
• Modify the toString of Stock class to display as
“Company: qty shares” (i.e., “Apple: 10 shares”)

StockIO class
Create a StockIO class that is used to read from and write to a text file using an ArrayList. Make sure to use a delimiter between the fields; it does not have to be the # character. Example format of the file is:

Apple#100#55.0#80.0
Intel#50#75.0#70.0

This class should have two methods.
• getData—reads data from file, returns data in array list of stock objects
• saveData—writes data from an array list to the file in proper format
The file name will be an instance variable that you can set with a parameterized constructor, or with a separate method.

GUI class
Note that you will need to add an ArrayList to your GUI class to manage the data to/from the file. It will act as a parallel array to your DefaultListModel. Any time you add a stock, you must add it in BOTH places. Any time you remove a stock, you must remove it in BOTH places.

File—open should prompt for file name using JOptionPane, read the file and populate the JList.
File—save should prompt for file name to save data from JList to.
File—exit should exit the program.

The total value of the portfolio should be displayed at all times and updated anytime a stock is added or removed.
