Creating and Array from an Array

[Masamune1059]

Hi, im trying to create a new array from and existing one i have but without the duplicates, then i can use this new array to populate a dropdown menu.

My problem is this, when i run the program i come across ""Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: 33"" and i dont know how to get around it.

I've included the problem area (i think) below, and the full netbeanz file is here MEGAUPLOAD - The leading online storage and file delivery service.

Any help would be greatly appretiated

   public Arrays()
   {
      // Finds amount of different Route Codes (a)
      int a = 0;
      for (int i = 0; i < routecode.length; i++)
      {
         if (routecode[i].equals(routecode[i + 1]))
         {
            System.out.println("Entered if");
         }
         else
         {
            System.out.println("Entered else");
            a++;
            System.out.println(a);
         }
      }

      //Puts route codes into a new string without duplicates
      String[] menu = new String[a];
      for (int i = 0; i < routecode.length; i++)
      {
         if (routecode[i].equals(routecode[i + 1]))
         {
            System.out.println("if");
         }
         else
         {
            System.out.println("else");
            menu[i] = routecode[i];
            System.out.println(menu[i]);
         }
      }

   }

Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: 33

Remember that the indexes for arrays go from 0 to the length-1. An index >= the length of the array is Out Of Bounds.

Look at the statement with the error and see what index used in that statement is past the end of the array.
If you can not tell, add printlns to print out ALL of the indexes values used on the line so you can see which one is out of bounds.
The index values are what is inside of the []s
