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
