This is the question –  In Ch

This is the question – 

In Chapter 2, you created an application named QuartsToGallonsInteractive that accepts a number of quarts from a user and converts the value to gallons. Now, add exception-handling capabilities to this program and continuously reprompt the user while any nonnumeric value is entered.

Code I was given – 

import java.util.Scanner;
class QuartsToGallonsInteractive
   public static void main(String[] args) 
      final int QUARTS_IN_GALLON = 4;
      int quartsNeeded = 18;
      int gallonsNeeded;
      int extraQuartsNeeded;
      Scanner input = new Scanner(;
      System.out.print(“Enter quarts needed >> “);
      quartsNeeded = input.nextInt();
      gallonsNeeded = quartsNeeded / QUARTS_IN_GALLON;
      extraQuartsNeeded = quartsNeeded % QUARTS_IN_GALLON;
      System.out.println(“A job that needs ” + quartsNeeded +
         ” quarts requires ” + gallonsNeeded + ” gallons plus ” +
         extraQuartsNeeded + ” quarts.”);
