I put ArrayLists into an ArrayList. I send this ArrayList to a class. In that class I will use the ArrayLists. In this class i defined a new ArrayList. In this class every time the timer elapsed I will get the next ArrayList to this new ArrayList that I defined in the class. But when i wrote
arrListInClass = mainArrList[counter];
error occurs because of casting, it cannot cast object to arraylist. help?!?

Try this:

(Toggle Plain Text)

arrListInClass = (ArrayList)mainArrList[counter];

This "typecasts" the object contained in the arraylist to the ArrayList type before copying it into your variable.
