title: j2me - Does a List have any property to keep track of 'key' that identify the item
body: <p>How do you usually deal with Lists and the fact that they don't have a property to clearly identity an specific item ?
  So far, the only solucion I could come up with is to put the key I use at the beginning, followed by a hyphen  and the text that is shown on every item.
  This way when I retrieve the text from the selected item I can get the key for the item.</p>
  
  <p>This is how I do it, but surely there's gotta be a better solution and I'd really like that you could share your experience in this kind of scenarios.</p>
  
  <p>Thanks in advance.</p>
