Pub-Sub implements Observer pattern.Per my understanding Publisher is Subject and Subscribers are Observers. So publishers state change will be notified to Observers whenever there is a state change.
Do I need to implement any interface method for sending the message in the Subject (
Which is the right approach to implement the Observer (
Observer Class implements
's onMessage(message) (or) Observer Class implements
's handleNotification(notification, callback)/
