   public class Main {
   public static void main(String[] args) {
   Scanner scanner = new Scanner(System.in);
   System.out.println("Weight:");
   int weight = scanner.nextInt();

    System.out.println("size:");
   

   double size = scanner.nextDouble();

   double bki = (weight / (size * size));

   if (bki < 18.5); {

    System.out.println("Normal Weak.");
   

   }
   else if (bki >= 18.5 && bki < 25) {

    System.out.println("Normal.");
   

   }
   else if (bki >= 25 && bki < 30) {

    System.out.println("Very Overweight");
   

   }
   else if (bki >= 30) {

            System.out.println("Very Very Overwight");
   

   }
