Retrieve Array from an ArrayList May 19th, 2010, 3:27am   I've stored Arrays in an ArrayList by doing so: Code: a = split(rDataLines[i], ";"); dataList.add(a); When I try to retrieve the first array from the ArrayList by using the following code, processing breaks and throws an ClassCastException. Code: ArrayList b = (ArrayList)dataList.get(0); println(b.get(0)); println(b.get(10)); Any idea how to retrieve the first object (array) from the ArrayList as an 'usable' array instead of the default Object?
