Small CODE snippet I found today...



  • public String getName(int id) throws Exception {
            ArrayList contents = getContents();
            ActionDTO action = (ActionDTO)contents.get(id - 1);
            return action.getActionName();
        }   

     

    for the record getContents makes no guarantees on the order of whats returned.  Even if it did that alone wouldn't be enough to make this reliable. 



  • I have a system like this! It's my wallet. Sadly, it's a zero-based wallet, so in order to retrieve the first dollar, I have to subtract one from it.
