Description
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 200 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
BMI: 21.9
BMI Category: normal
Max heart rate: 170
Enter name or X to quit: X
