CIS355A Week 1 LabDeveloping 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 persons 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 200 minus a persons 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

BMI: 21.9

BMI Category: normal

Max heart rate: 170

Enter name or X to quit: X

CIS355A Week 2 LabDeveloping 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 weeks 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
