Graph
hi everyone i'm currently working on graph program,i dont want to
draw a graph. but i want to use vectors to display the edges
that are connected to each other in a URL.
so basically the nodes will be the links and i have to display what links are connected to each other.
I have created the following program
import java.util.*;
import java.io.*;
class graph {
Vector nodes=new Vector();
Vector edges=new Vector();
public graph() {
Vector nodes=new Vector();
Vector edges=new Vector();
graph g;}
graph addnode(Object x) { if (!nodes.contains(x)) {nodes.addElement(x);
Vector w=new Vector();
edges.addElement(w); } return(new graph(nodes,edges)); }
graph addedge(Object start, Object finish) {
if (nodes.contains(start) && nodes.contains(finish))
{
int posOfStart=nodes.indexOf(start);
int posOfFinish=nodes.indexOf(finish);
Vector w = (Vector)(edges.elementAt(posOfStart));
w.addElement(new Integer(posOfFinish));
nodes.setElementAt(w,posOfStart);
}
return new graph(); }
//toString() { }
public static void main(String [ ] args) { graph g = new graph(); g.addnode("****");
g.addedge("****","****"); }
}
but i keep getting errors as follows:
C:\jdk1.2.1\graph.java:13: Wrong number of arguments in constructor.
edges.addElement(w); } return(new graph(nodes,edges)); }
^
1 error
Tool completed with exit code 1
What i want is for user to enter a URL and integer (whihc represents
the level of depth in the URL) and for the program to display
what links are connected to each other

thank you very much for your help in advance
