Observer/observable objects with MVC pattern
===

I have this situation:

An object that it's observable and another object that it is observer.

the observer has a method `update(Observable obs,Object obj)` that receive through `notifyObservers` the object changed.when observer receives the notify, update method prints the object changed. I want print out the result in a gui that implements MVC pattern.I'm following  this guide [MVC pattern][1].
My idea is to make the `Controller` the observer. something like that:

    public class Controller extends AbstractController implements Observer 
    {
    	public static final String TOTAL_HIT_COUNT_PROPERTY = "Total Hit";
    	
    	public void changeTotalHitCount(long new_total_hit_count)
    	{
    		setModelProperty(TOTAL_HIT_COUNT_PROPERTY, new_total_hit_count);
    	}
    
    	@Override
    	public void update(Observable o, Object arg) 
    	{
    		
    	}
    }
but I don't know if it's a correct implementation!
