Hi,
Judging from the direction of message passing in an interaction diagram, we can infer 'navigability' between classes. Am I correct in my statement?
If so, which three options in the following question are correct?
When it comes time to write code, an interaction diagram can quickly provide information on which of the following? (choose three)
a)Navigability of associations
b)The sequence of method calls
c)Conditions under which a message is sent
d)State changes in an object
e)Iteration in the control flow
a, b, c, e - four of these choces seem correct to me.
Should (a) be excluded because navigability can not be understood QUICKLY?
Should (e) be excluded because 'control flow' in this context does not imply 'the conditions under which the messages are sent'?
Please comment.
Thanks.
