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 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) and  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
