How to divide the controller?

Question

My View-Controller

public class MainForm implements java.util.Observer{
@Override
    public void update(Observable o, Object arg) {
        System.err.println("update View ....");
        this.textField_15.setText(String.valueOf(model.getThermalConductivity()));
            /*
*****
*/


    }
}

In the model I use methods

setChanged();
notifyObservers();

All events model updates are processed in the method "update"

The MainForm looks like your view to me as it has text fields and other GUI thingies. Maybe I'm wrong, but I think of the GUI listeners as more of the control aspect. — Hovercraft Full Of Eels, May 30 '11 at 17:43
First off, avoid using java.util.Observer, this is probably the worst implementation of the observer pattern. — jfpoilpret, May 30 '11 at 20:28
@jfpoilpret: [`java.util.Observable`](http://download.oracle.com/javase/6/docs/api/java/util/Observable.html) has the advantage of being simple and understandable, but your point is otherwise well-taken. — trashgod, May 30 '11 at 23:13

You might enjoy trying this example. For simplicity, the model extends Observable, but several other approaches are mentioned with links to examples.
