title: Sending data from observer to observable
body: <p>I have a java application that implements the <em>observer/observable</em> pattern. In my MVC model, the observer class is the View, and the observable class is the controller. </p>
  
  <p>Every changes in my observable class are sent to the observer one using <code>setChanged();</code> and <code>notifyObservers();</code> instructions, and the observer class is changed using the update method. </p>
  
  <p>This works allright, the problem is that during the execution, sometimes, the user has to interact with the application using some <code>JButtons</code> defined in the observer class, but I don't know how to send this information to the observable class so that this continues its execution considering the user interaction. in fact, I don't even know if it is possible to do it.</p>
  
  <p>Any help will be appreciated.</p>
