Curt Arnold If the "refChild" is null then the "insertBefore(newChild,refChild)" method inserts the node "newChild" at the end of the list of children. Retrieve the second employee and invoke the "insertBefore(newChild,refChild)" method with refChild=null. Since "refChild" is null the "newChild" should be added to the end of the list. The last item in the list is checked after insertion. The last Element node of the list should be "newChild". 2002-06-09
