public LinkedList() Constructs an empty linked list, with the head, previous, and current nodes null. public boolean isEmplty() Returns true if the list is empty and false otherwise. public void insert(Object o) Creates a node containing the object o, inserting it before the current element. public void remove() Removes the current element. public Object getData() Gets the data field from the current element. Returns null if the current element is null. public boolean atEnd() Returns true if the current element is null and false otherwise. public void advance() If current is not null, advances the precious and current references. public void reset() Resets the current reference to refer to the head of the list. public void display() Prints each element of the list on a separate line.
