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”

How to divide the controller?

Answer 1

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