CIS 355A Week 6 Lab Database Stocks4U Portfolio Management System
OBJECTIVES
Add persistent data storage to your Week 5 Lab using the MySQL Database.
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 MySql Database.
FUNCTIONAL
REQUIREMENTS
- The functional requirements of the Stocks4U
application have not changed, and the Graphical User Interface has not
changed from Week 5.
StockIO
class
Modify the StockIO class to read and write the stock
information to and from a MySQL database. Called “StocksDB”
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 data base in proper
format
- deleteStock—deletes the identified stock from the database
- updateStock—updates the identified stock in the
database.
The database connection string will be stored as a
constant in the StockIO class.
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 open the database, retrieve the existing records and display the
existing records.
File—save should save all records, new and old, back to the database.
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.
