when using Graph.getVertices().iterator(), the iterator misses the first vertex added in the graph, eg:
For the vertices: ---------------- vertex v1 vertex v2 vertex v3
Iterator i = g.getVertices().iterator();
for( vertex v = i.next(); i.hasNext(); v = i.next() ) //Do something
returns only v2 and v3. g.getVertices().toArray() returns all vertices.
Hello,
The problem is your call for next() in the for loop: for( vertex v = i.next(); i.hasNext(); v = i.next() )
the first expression skips the first element.
Please try: ;
for(Iterator i = g.getVertices().iterator(); i.hasNext(); /* EMPTY */ ) { Vertex v = (Vertex) i.next() //Do something }

aaah, my mistake, its a long timme since i last used the iterator interface ;-)
thx for the patience!
