Answer 1

Answer:

Answer 2

I guess this what you are looking for :

When two or more objects are added as listeners for the same event, which listener is invoked first to handle the event.

1. There is no way to determine which listner will be invoked first.
2. The last object that was added as listner.
3. It is impossible to have more than one listner for a given event.
4. The first object that was added as listner.

The correct answer is

1.There is no way to determine which listner will be invoked first.

As when 2 or more objects are are added as listner for same event it is not possible to evaluate which listner would get provoked or invoked first.

It could be first object or the last object.

And it is possible to have more than one listner for a given event.
