Question

How can I call call the retriveRoom method and return the rooms[connectedRoom] object, and use the objects properties inside of the method in the ROOMS CLASS? Any help is greatly appreciated. It is saying it cannot find the room.numLights in the system.out.println???

 //MASTERCONTROLPANEL CLASS

 public static Object retrieveRoom(int connectedRoom){
    connectedRoom -= 1;
    return rooms[connectedRoom];
    }


 //ROOMS CLASS
 public void roomHeatLoss(){
    //I am having problems with the line below//
    ***Object room***= MasterControlPanel.retrieveRoom(1);
     System.out.println("" + room.numLights);
}

Answer 1

Try changing the method to return a Room or casting the Object prior to invoking the method.

Either this:

public static Room retrieveRoom(int connectedRoom){
   return rooms[connectedRoom];
}

or this:

public void roomHeatLoss(){
    Room room = (Room)MasterControlPanel.retrieveRoom(1);
}

You don’t say what your problem is. That would help us to figure out what to suggest.
