BCS2233 OOP: Thinking in Objects

Berikut adalah program untuk mengira BMI dan menyatakan status yang sepadan. Tukarkan kepada kaedah OOP.

import java.util.Scanner;

public class ComputeAndInterpretBMI {
  public static void main(String[] args) {
    Scanner input = new Scanner(System.in);
    
    // Prompt the user to enter weight in pounds
    System.out.print("Enter weight in pounds: ");
    double weight = input.nextDouble();
    
    // Prompt the user to enter height in inches
    System.out.print("Enter height in inches: ");
    double height = input.nextDouble();
    
    final double KILOGRAMS_PER_POUND = 0.45359237; // Constant
    final double METERS_PER_INCH = 0.0254; // Constant 
    
    // Compute BMI
    double weightInKilograms = weight * KILOGRAMS_PER_POUND; 
    double heightInMeters = height * METERS_PER_INCH; 
    double bmi = weightInKilograms / 
      (heightInMeters * heightInMeters);

    // Display result
    System.out.println("BMI is " + bmi);
    if (bmi < 18.5)
      System.out.println("Underweight");
    else if (bmi < 25)
      System.out.println("Normal");
    else if (bmi < 30)
      System.out.println("Overweight");
    else
      System.out.println("Obese");
  }
}
