The following program is in Java, please solve carefully.

The following function is supposed to take a list and return a copy of the list with the order of the elements reversed. However, it doesn't work as intended. Point out the problems, and explain how to fix them. rev public static List reverse(List lst){ List rev; if (1st instanceof ArrayList){ = new ArrayList(); } else { rev = new LinkedList(); } Iterator it = lst.listIterator(1st.size()-1); while (it.hasPrevious()){ rev.add(1, it.previous()); } return rev; }
