Question

Hi, Can you help me know the kind of parameter do I pass while I call the function "printParents" below. This is a program to detect if the graph is Bi-Partite or not using a DFS algorithm. I will have follow up questions on this. Thank you!

public void printParents (PrintWriter output) {
int v;
output.println("Parents in BFS tree:");
output.printf ("Vertex: ");
for (v = 1; v <= nVertices; v++)
output.printf ("%2d ", v);
output.println();
output.printf("Parent: ");
for (v = 1; v <= nVertices; v++)
output.printf ("%2d ", vertices[v].parent);
output.println();
}// end of printParents

Answer 1

To call the printParents function you need to pass the PrintWriter class object because in the method they are writing the statements to a file

So you should open an file for the same

// you shoud name your file accordingly

PrintWriter pw = new PrintWriter("output.txt");

so now you need to pass pw to printParents method
