Java.util.Observable, clients will complete their update () before continuing

Question

When i call:

setChanged();
notifyObservers();

in the class java.until.Observable, all listening Observer objects complete their udpate () methods - if we work in the same thread - before the class java.until.Observablecontinues to work?

This is important because I will send several messages using the method notifyObservers(Object o)in fast concession, it is important that each Observer class complete its method to a new one.

I understand that the execution order for each Observer class can change when called notifyObservers()- it is simply important that the execution order of the method for each individual instance is in order.
