my problem is, the data of my arraylist is erased when using it in another class, I have the crud add and consult works in a class, and both work I think and consult and everything is fine, but when I restore it works in a separate class , and I walk the arraylist does not work there are no objects, which must be added to make it work? inheritance or something like that? Sorry I'm a newbie just learning
