USE OBJECT ORIENTATED PROGRAM DESIGN TO SOLVE PROBLEM

Create a class BMI. (Body Mass Index)

BMI = 703*weight / height * height //Weight in lbs, height in inches

The BMI class should also return the person’s name using the program.

Create a method for calculating BMI and round BMI to 1 decimal place

Create a method for returning the BMI possibilities

Severe Thinness < 16

Moderate Thinness 16.1 – 17

Mild Thinness 17.1 – 18.5

Normal 18.6 – 26

Overweight 26.1 – 30

Obese Class I 30.1 – 35

Obese Class II 35.1 – 40

Obese Class III > 40.1

Construct your class to contain multiple constructors.

Use the this. Keyword if you like.

Execute a few versions of the program

Passing different values into the program using different parameter and argument configurations.

Output:

The BMI for John is 26.5 which is the Over Weight Category.

or

The BMI for Susan is 17 which is in the Moderate Thiness Category

Explanation / Answer

public class BMI {

   private String name;
   private double height;
   private double weight;
   /**
   * @param name
   * @param height
   * @param weight
   */
   public BMI(String name, double height, double weight) {
       super();
       this.name = name;
       this.height = height;
       this.weight = weight;
   }
  
   public double getBMI(){
       return 703*weight / height * height; //Weight in lbs, height in inches
   }
  
   public String getBMIType(){
      
       double bmi = getBMI();
      
       if(bmi <= 16)
           return "Severe Thinness";
       else if(bmi>=16.1 && bmi <= 17)
           return "Moderate Thinness";
       else if(bmi>=17.1 && bmi<=18.5)
           return "Mild Thinness";
       else if(bmi>=18.6 && bmi<=26)
           return "Normal";
       else if(bmi>=26.1 && bmi<= 30)
           return "Overweight";
       else if(bmi>=30.1 && bmi<=35)
           return "Obese Class I";
       else if(bmi>=35.1 && bmi<=40)
           return "Obese Class II";
       else
           return "Obese Class III";
   }
  
   public void displayBMI(){
       System.out.println("The BMI for "+name+" is "+String.format(".1f", getBMI())+" which is the "+getBMIType());
   }
}

################## Test Class #################

public class TestBMI {

   public static void main(String[] args) {
      
       BMI b1 = new BMI("Alex", 23, 43.23);
      
       b1.displayBMI();
   }
}

/*

Output:

The BMI for Alex is .1f which is the Obese Class III
