Hello guys,

I'm getting the following error:



The thing is that I'm not finding where the error is exactly. Here comes my code:



What am I doing that I should not do? What's so wrong? For as far as I know that's the only way of doing what I want. And I still don't see my error.

Anyone could help? Thanks

Your error is clear. While you are iterating over listAcumulador with
ListIterator acumuladorIt, you are applying add and remove methods to
listAcumulador -- this is enough to cause the exception.

I don't understand your code so I can't suggest specific code, but
among your options is to (1) use *ListIterator's* add and remove methods,
or (2) make a copy of your list and iterator over the copy, but
change the original list (be careful if you choose to do this!).
 
It is sorta covered in the JavaRanch Style Guide.
