For this question you will be using a doubly linked list containing Strings and Node class which contains these methods: Node( String nodeData ) getNextNode( ) getPrevNode( ) setNextNode(Node ref) setPrevNode(Node ref) Given a reference to a node named "current" in the list that is not at the list head and not at the list tail, write a code snippet to insert a new node before the current node that contains the String "CAT". There is no need to address the list being empty.
