java - Observer / Observable to PropertyChangeListener

Question

Using Observer and Observable method update() would look as following:

@Override
    public void update( Observable o, Object arg ) {
        switch( (GameState) arg )
        {
            case NEW_GAME:
                setNewGame();
                break;

            case CHECK:
                setGameCheck( (Model) o );
                break;
        }
    }

I want to replace it with PropertyChangeListener since Observer and Observable are deprecated. I don't know how to update depending on GameState. Btw is there an equivalent of notifyObserver in PropertyChangeListener?
