Hi there guys!
Can someone help me with the part add tour,when I run it, its always print the same line 2 times and then when I enter the data for guide tour which should be store in the memory, but when using the display method it didn't appear like i want.

      {

         for (int i = 0; i < tourCount; i++)
         {
            tours[i].display();
            System.out.println();
         }
      }
   }
   public static void addTourBooking()
   {
      
   }
   public static void listTourBookings()
   {
      
   }

   public static void hireEquipment()
   {
      
   }
   public static void listEquipmentHires()
   {
     
   }
   public static void cancelBooking()
   {
   
   }
   
   public static void loadData()
   {
     
   }
 
   public static void saveData()
   {
     
   }
}

And 1 more thing that how can i save the data in array into a file?
I attached the rest of the class so if someone want to run it.

Very nice

Line 203 is the problem--

203 type = console.nextLine().toUpperCase();

Change it to--

type = console.next().toUpperCase();

--and you should be golden.

I've not checked if Alex is correct, but as per your question regarding the storage of your array information. It can so easily be done by writing the entire array object to a file.

The is a ObjectOutputStream class and if you check out the API you'd see an example of how this would be done. Alternatively you can write the contents of the array in a text file using a looping structure that reads each element of the array. You can then read the contents back with the Scanner class.

Whoops i was tired when I replied, it's definitely not the solution.

I was trying to figure out if it was the do-while loop repeating or if it was the information on the screen reprinted and it's obviously not the 2nd option. My apologies.

do
         {
            System.out.print("Enter Tour Type (G for guide tour, U for no guide tour): ");

			String temp2 = console.nextLine();//apparantly there was still data in the stream that needed to be flushed?

            type = console.nextLine().toUpperCase();

            System.out.print("");

         } while (!type.equalsIgnoreCase("G") && !type.equalsIgnoreCase("U"));
