what's difference between a callback and observer pattern in java -
i going through following link in stack on flow
how perform java callback between classes?
in particular question answer 18 refers callbacks , answer 9 refers observer pattern.
i unable distinguish difference between both.
can please explain these 2 approaches differ?
a callback piece of code provide class , gets called @ point. ex:
serverconnectionhandler = new serverconnections(new itypedcallback<socket>() { @override public void execute(socket socket) { // socket here } });
the observer's pattern design pattern based on callbacks. can find more details here http://en.wikipedia.org/wiki/observer_pattern.
