probably something like

Node lastNode = null;

Node currentNode = head;

// walk thru the list of nodes until we get to the last node
while (currentNode != null) {
  lastNode = currentNode;
  currentNode = currentNode.getNext(); 
} // while

// now that we have the last node, append a new node to it.
lastNode.setNext( new Node(item) );
