CIS355A Business Application Programming

CIS355A Week 1 Lab - Developing an OOP Console Application

OBJECTIVES
• Create a class in java with appropriate methods.
• Process user input with the class using the scanner for keyboard input and console output.

PROBLEM: Health Profile Console Program
GymsRUs has a need to provide fitness/health information to their clients, including BMI and maximum heart rate. Your task is to write a console program to do this.

Body mass index (BMI) is a measure of body fat based on a person’s height and weight. BMI can be used to indicate if you are overweight, obese, underweight, or normal. The formula to calculate BMI is

The following BMI categories are based on this calculation.
Category BMI Range
Underweight less than 18.5
Normal between 18.5 and 24.9
Overweight between 25 and 29.9
Obese 30 or more

Max heart rate is calculated as 220 minus a person's age.

FUNCTIONAL REQUIREMENTS
Design and code a class called HealthProfile to store information about clients and their fitness data. The attributes (name, age, weight, and height) are private instance variables. The class must include the following methods.

method Description
setName Receives a value to assign to private instance variable
setAge Receives a value to assign to private instance variable
setWeight Receives a value to assign to private instance variable
setHeight Receives TWO inputs (height in feet, inches).  Converts and stores the total INCHES in private instance variable
getName Returns private instance variable
getAge Returns private instance variable
getWeight Returns private instance variable
getHeight Returns private instance variable (inches)
getBMI Calculates and returns BMI
getCategory Returns category based on BMI
getMaxHR Calculates and returns maximum heart rate

Create a SEPARATE TEST CLASS, Lab1Main, to prompt for user input and display output using the HealthProfile class. Process multiple inputs using a loop. You can assume all user input is valid.

SAMPLE OUTPUT

Enter name or X to quit: John Smith
Your age: 35
Your weight: 200
Your height - feet: 6
Your height - inches: 0

Health Profile for John Smith
BMI:  27.1
BMI Category: overweight
Max heart rate: 185

Enter name or X to quit: Ann Jones
Your age: 50
Your weight: 120
Your height - feet: 5
Your height - inches: 2

Health Profile for Ann Jones

CIS355A Week 2 Lab - Developing a GUI Application

OBJECTIVES
• Create a GUI that uses JTextField, JLabel, and JButton.
• Write event handlers to process user data.

PROBLEM: Health Profile App
GymsRUs would like to replace their console program with an updated app using a graphical user interface. You will use the HealthProfile class that you created in the Week 1 Lab and build a GUI for it.

FUNCTIONAL REQUIREMENTS
Make sure your HealthProfile class from the Week 1 Lab is in a named package, not default (i.e., package lab1).

You must ADD the project that contains the HealthProfile class to this week’s project by
right click project, go to properties; and
click Libraries, Add Project, click OK.

Then you will be able to reference your existing class as
import lab1.HealthProfile.

Your project will have three classes:
• HealthProfile class from Week 1 Lab
• HealthProfileGUI class
• Lab2Main class

Your HealthProfildGUI class should have the following components (see sample GUI below).
• JTextField objects to enter:  name, age, height in feet, height in inches, weight in pounds 
• JButton objects to display results, clear the GUI
• JTextField objects to display the BMI, category, and max heart rate
• JLabels to describe all textboxes
You are free to layout and design your GUI as you like as long as it includes these components.

Add default and parameterized constructors to your HealthProfile class. The parameterized constructor should have five arguments: the name, age, weight, height in feet, and height in inches. Note it should convert the height to inches to store in the private instance variable.
Code event handlers for each button:
• Display: Make sure all user input is present and valid Use the HealthProfile class to process the data Display the results on the GUI
• Clear Clear all text boxes on the GUI

CIS355A Week 4 Lab - Processing Arrays of Objects Stocks4U

OBJECTIVES
• Create a GUI that uses JList and JTabbedPanes.
• Process multiple objects in an ArrayList.
• Code event handlers for multiple events.

PROBLEM: Stocks4U Portfolio Management System
Stocks4U needs to develop an app for you to manage your stock purchases. You should be able to store a list of stock purchases, view the individual stocks, add and remove stocks.

FUNCTIONAL REQUIREMENTS
You can code the GUI by hand or use NetBeans GUI builder interface.

The GUI should have two tabs using JTabbedPane.
• One tab ("Show stocks") should have
 o a JList to display all the stock purchases;
 o a text field or label to display information about a particular stock; and
 o a JButton to remove a stock.
• One tab ("Add stock") should have textboxes, labels, and a button to input a stock.

Create a Stock class to manage the stock activity. It should have private instance variables of
• company name;
• number of shares;
• purchase price; and
• current price.
Create a default and parameterized constructor.
Create sets/gets for all instance variables.
Create a get method to calculate and return the profit or loss. This would be calculated as
 Number of shares * (current price – purchase price).
Create toString to display the name of the stock.

As you add stocks, they are displayed in the JList.
If you select an element in the JList, the gain or loss is displayed in the label or text field.
If you select an element in the JList and click Remove, the stock is removed from the list.

CIS355A Week 5 Lab - File Processing Stocks4U

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.
