What will be the result after running the following code?

interface iMap
{
     public function updateCoords(xPos:Number, yPos:Number):void
}
interface iNav
{
     public function panTo(xPos:int, yPos:int):void
}

public class NavMap implements iMap, iNav
{
     public function NavMap()
     {
        trace ("navmap");
     }
     public function updateCoords(xPos:Number, yPos:Number):void
     {
         trace ("updating...");
     }
public function panTo(xPos:int, yPos:int):void
     {
         trace ("panning to: ", xPos, yPos);
     }
}

var navMap:NavMap = new NavMap();
navMap.updateCoords(250, 250);
