Listners

[Anonymous]

Which statements are true about listeners?
A. The return value from a listener is of boolean type.
B. Most components allow multiple listeners to be added.
C. A copy of the original event is passed into a listener method.
D. If multiple listeners are added to a single component, they all must all be friends to each other.
E. If the multiple listeners are added to a single component, the order [in which listeners are called is guaranteed].
Ans B,C
But I think C is not correct. Pls help.

original copy is sent(i.e call by value)it can be received by only one listener ,so c is correct

Hi Joe Casad:
Which statements are true about listeners?
A.The return value from a listener is of boolean type. //FALSE, the return type is void
B.Most components allow multiple listeners to be added. // TRUE
C.A copy of the original event is passed into a listener method. // FALSE, a copy of reference is passed
D.If multiple listeners are added to a single component, they all must all be friends to each other. // FALSE
E. If the multiple listeners are added to a single component, the order [in which listeners are called is guaranteed]. // FALSE, the order is NOT guaranteed
Ans B only
