Question 6

Given the code fragment:

Which code can be added to register both of these methods to receive BankEvent notifications only if an instance of BankActivityService is already instantiated in the current context?

@Observes(notifyObserver=IF_EXISTS) on line 3 and line 6

@Observes(during=IN_PROGRESS) on line 1

@Observes(during=AFTER_COMPLETION) on line 1

@Observes(notifyObserver=IF_EXISTS) on line 4 and line 7 before method parameter declaration

Correct Answer: D

To register methods to receive notifications only if an instance of BankActivityService is already instantiated in the current context, you must use the @Observes annotation with the notifyObserver parameter set to IF_EXISTS before the method parameter declaration. This ensures that the methods are only invoked if the observer instance is already available. Therefore, the correct code is @Observes(notifyObserver=IF_EXISTS) on line 4 and line 7 before the method parameter declaration.
