Developing An OOP Console Application

Lab: Developing An OOP Console Application

  • 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 RangeUnderweight less than 18.5Normal between 18.5 and 24.9Overweight between 25 and 29.9Obese 30 or more
Max heart rate is calculated as 200 minus a person’s age.

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 descriptionsetName Receives a value to assign to private instance variablesetAge Receives a value to assign to private instance variablesetWeight Receives a value to assign to private instance variablesetHeight Receives TWO inputs (height in feet, inches).  Converts and stores the total INCHES in private instance variablegetName Returns private instance variablegetAge Returns private instance variablegetWeight Returns private instance variablegetHeight Returns private instance variable (inches)getBMI Calculates and returns BMIgetCategory Returns category based on BMIgetMaxHR 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.
