I am sorry to post such lengthy code but I just can't get it to work. I load up a LinkedList form disk and sort it and try to access the objects inside, but it throws the Exception. Really bummed I don't know what to do. I have bolded the trace to exception, any help would be great!
Don't use sezona.remove(game). Use iterator.remove() . Not only will the exception go away, but the performance will be much better for long lists. You can't call add() or remove() on a Collection while you're iterating over it, or the Iterator will throw an exception, as you found out.
