question: returns an iterator to this stack that iterates through the items in lifo order . concode_field_sep Node<Item> next concode_elem_sep Item item concode_elem_sep Node<Item> current concode_elem_sep Node<Item> first concode_elem_sep int N concode_field_sep Item pop concode_elem_sep Item next concode_elem_sep int size concode_elem_sep boolean isEmpty concode_elem_sep String toString concode_elem_sep boolean hasNext concode_elem_sep void push concode_elem_sep void remove concode_elem_sep Item peek
target: Iterator < Item > function ( ) { return new ListIterator < Item > ( first ) ; }
