Question

You've created an application named quartstogallonsinteractive that accepts a number of quarts from a user and converts the value to gallons. Now, add an exception-handling capabilities to this program and continuously reprompt the user while any nonnumeric value is entered. Save the file as QuartsToGallonsWithExceptionHandling.java

What I have will compile with no errors but doesn't do anything to prompt user for values.

import java.util.Scanner;
class QuartsToGallonsInteractiveExceptionHandling
{  
   public static void main(String[] args)
   {
     // Set your variables
       Scanner input = new Scanner(System.in);
       final int>        int quarts;
       boolean isGoodUserEntry = true;
     
      while(!isGoodUserEntry)
      {
   System.out.println("Enter number of quarts");
      
            try{
       
              quarts = Integer.parseInt(input.nextLine());
              int gallons = quarts / oneQuart;
              quarts = quarts % oneQuart;
            
              System.out.println("A job that needs " + gallons + " gallons plus " +
                       quarts + " quarts.");
            
              isGoodUserEntry = false;
         }
       // Catch the exception if it's not good
         catch(Exception e){
           
             System.out.println("Exception: " + " NumberFormatException");
           
         }
      
         }
      
   }
}

try{

quarts = Integer.parseInt(input.nextLine());
int gallons = quarts / oneQuart;
quarts = quarts % oneQuart;
