The observer pattern

[Tony Johansson]

Hello experts!

How can I use the parameters of this update to prevent executing the row of
body of this update when the update is called.
I'm using the observer pattern.
public void update(Observab le o, Object arg)
{
textField.setTe xt(String.value Of(subject.getV alue()));
}

Many thanks!
//Tony

Under what conditions do you not want to execute the statement in update()?
