Solution

import java.util.Scanner;

public class HelloWorld

{

    public static void main(String[] args)

    {

         // Create a Scanner object

         Scanner input = new Scanner(System.in);

         // Create constant value

         final double METERS_PER_FOOT = 0.305;

 

         // Prompt user to enter a number in feet

         System.out.print("Enter a value for feet: ");

         double feet = input.nextDouble();

 

         // Convert feet into meters

         double meters = feet * METERS_PER_FOOT;

 

         // Display results

         System.out.println(feet + " feet is " + meters + " meters");

    }

}

OUTPUT
