Question

Java 1. USE OBJECT ORIENTATED PROGRAM DESIGN TO SOLVE PROBLEM Create a class BMI. (Body Mass Index) BMI = 703 astir weight/height astir 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 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.1 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 2. Create a computer program that will calculate the range for 3 different vehicles. The program should create a "programmer created" class, where 3 int objects are created passengers, fuel capacity, mpg. Create a voidQ method inside the "programmer created " class to calculate vehicle range, range = fuel capacity * miles per gallon. Each Vehicle type should have unique values for number of passengers, fuel capacity, and miles per gallon. Follow the sample below and return information on 3 vehicle types. Sample Output://Create similar output for 3 Vehicle Types The minivan carries= 7 The minivan has a fuel capacity of = 16 The minivan mpg = 21 The minivan has a range of: 336 miles

       System.out.println("The BMI for '"+name+"' is "+ bmi+" which is '"+description+"' cattegory");
  

   }
   //Method which calculate the BMI
   public static double calculateBMI (double height, double weight) {
   return weight * 703 / (height * height);
   }

}

______________________________________________________________________________

output:

:: This program will calculate your body mass index, or BMI ::
Enter the Name :John
Enter your weight, in lbs: 220
Enter your height, in inches: 68
The BMI for 'John' is 33.44723183391003 which is 'Obese Calss 1' cattegory
