    • notifyObservers

      public void notifyObservers()
      If this object has changed, as indicated by the hasChanged method, then notify all of its observers and then call the clearChanged method to indicate that this object has no longer changed.

      Each observer has its update method called with two arguments: this observable object and null. In other words, this method is equivalent to:

      notifyObservers(null)

    • notifyObservers

      public void notifyObservers(Object arg)
      If this object has changed, as indicated by the hasChanged method, then notify all of its observers and then call the clearChanged method to indicate that this object has no longer changed.

      Each observer has its update method called with two arguments: this observable object and the arg argument.

      Parameter:
      arg - any object.

    • setChanged

      protected void setChanged()
      Marks this Observable object as having been changed; the hasChanged method will now return true.

    • clearChanged

      protected void clearChanged()
      Indicates that this object has no longer changed, or that it has already notified all of its observers of its most recent change, so that the hasChanged method will now return false. This method is called automatically by the notifyObservers methods.
