You need a check for w.getElements() returning nothing. - Wrath of the Barclay

You need a check for w.getElements() returning nothing.

'Cos that will mean the return type isn't a string. Look at me go. I should take up java.

- You aren't returning anything in the 'else' case (n/m) (General Chat) - Brom, Oct 8, 17:06:26
  - I've tried with return " "; in the else statement, still gives the same error. (n/m) (General Chat) - Steve, Oct 8, 17:09:24

      - excuse me for being stupid, but how do I do that? (General Chat) - Steve, Oct 8, 17:21:22
        
        You have an ArrayList, which can be an array of any objects... (General Chat) - Brom, Oct 8, 17:25:57
        
        OK (General Chat) - Steve, Oct 8, 17:29:14
        
        Try calling ToString() on the object in the ArrayList? (n/m) (General Chat) - Brom, Oct 8, 17:32:19
      - You take it up the java (n/m) (General Chat) - pants, Oct 8, 17:12:21
        
        That doesn't even make any sense. (General Chat) - Arizona Bay, Oct 8, 17:13:22
      - WE HAVE A WINNER! (n/m) (General Chat) - Brom, Oct 8, 17:11:56
  - Ha ha, DING DING DING. (General Chat) - Arizona Bay, Oct 8, 17:07:12
- Is it the else case doing nothing rather than returning the empty string or suffen? (General Chat) - Arizona Bay, Oct 8, 17:02:40
