Lab: Developing OOP Console Application


CIS355AWeek 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

Gyms RUs 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 Health Profile 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
set Name Receives a value to assign to private instance variable
set Age Receives a value to assign to private instance variable
set Weight Receives a value to assign to private instance variable
set Height Receives two inputs (height in feet, inches)and converts and stores the total inches in private instance variable
get Name Returns private instance variable
get Age Returns private instance variable
get Weight Returns private instance variable
get Height Returns private instance variable (inches)
get BMI Calculates and returns BMI
get Category Returns category based on BMI
get Max HR Calculates and returns maximum heart rate

 

Create a separate test class, Lab1Main, to prompt for user input and display output using the Health Profile 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
