Please complete Depth first search adjacency list function.

note: I have included the constructor and image of adjacency list and text file, i have also included display function

// default constructor

public GraphLists(String graphFile) throws IOException

System.out.println("Parts[] = " + parts[0] + " " + parts[1]);

// create sentinel node

z.next = z;

// create adjacency lists, initialised to sentinel node z
