hey ive got to ArrayLists one is a node which holds the details of the node like id name and so on. the second arraylist holds the connection of these nodes or there family. the family contains a dad, mam and any number of children.
 what m trying to do is start with the first node which is a dad and connect it to the mam but there seems to be a problem when comparing the strings.
ive printed the start.nodeID and f.dad and they are the same, its probably a simple problem ive just bin lookin at it to long to see it any suggestions?

1.   Node start = (Node) nodes.get(0);
     for(Family f : famlies)
     {
       println(start.nodeID);
       println(f.dad);
       if(start.nodeID == f.dad)
       {
         println("he is a daddy");
         if(f.mam != "")
         {
           println("There is a mammy");
           for(Node n : nodes)
           {
             if(f.mam == n.nodeID)
             {
               println("Mammy printed");
               n.formatNode();
               n.draw();
             }
           }
         }
       }
     }
