                   propertyPrice[i] = Integer.parseInt(JOptionPane.showInputDialog(null,"ERROR: Please enter a number greater than 0.\nEnter the value of Property " + (i+1) + ":"
                           ,"Input", JOptionPane.INFORMATION_MESSAGE));
               // calculate total by adding on current propertyPrice
               total = total + propertyPrice[i];
           }
          
           // use a for loop to display all property information in the arrays
           for(int i = 0; i < numProperties; i++)
           {
               System.out.println(propertyAddress[i] + "\t\t" + propertyPrice[i]);
           }
           //display total
           System.out.println("\n\nTotal\t\t\t" + total);
           //alter outer loop- see if user wants to run another report
           runAnother = JOptionPane.showInputDialog(null,"Would you like to run another report? ","Input", JOptionPane.INFORMATION_MESSAGE);
           //validate runAnother
           while(!(runAnother.equalsIgnoreCase("y") || runAnother.equalsIgnoreCase("n")))
               runAnother = JOptionPane.showInputDialog(null,"ERROR: Please enter either \"Y\" or \"N\"\nWould you like to run another report? ",
                       "Input", JOptionPane.INFORMATION_MESSAGE);
       }
          
   }

}
