            while (scanner.hasNextLine())
            {
                
                String name = scanner.nextLine();
                if (name.equalsIgnoreCase("quit"))

                    break;
                }
                listOfNames.add(name);
                System.out.print("Enter the name: ");
            }
            System.out.println("listOfNames =  "+listOfNames);
        }
        finally
        {
            if (scanner != null)
            {
