Java - TreeMap with Comparator

http://www.java-samples.com/showtutorial.php?tutorialid=371

• OK example

• another example

http://repast.sourceforge.net/docs/api/repastjava/repast/simphony/space/graph/RepastEdge.html

• RepastEdge<T>

class EdgeCompare implements Comparator

{

   public int compare(Object a, Object b)

   {

      double weightA = (RepastEdge)a.getWeight();

      double weightB = (RepastEdge)b.getWeight();

      int returnVal;

      if (weightA < weightB)

      {

         returnVal = 1;

      }

      else if (weightA == weightB)

      {

         returnVal = 0;

      }

      else

      {

         returnVal = -1;

      }

      return returnVal;

   }

}

TreeSet ts = new TreeSet(new EdgeCompare);
