[Soot-list] Difference between G.v() and System

[Zeinab Lashkaripour]

Hi,
Sorry, this question of mine might seem too easy but,
I wanted to know if there is a difference between "System.out.println(..)" and "G.v().out.println(..)"

G.v() for the soot global vars and System for the rest of the vars?

Another question related to outputting data is: for outputting a list in soot do I need a iteration through the list or not?
Because I have written an analysis that I think it has a little bit of problem, therefore I can not get the answer to the above question by inspecting its output. 
 
Regards,
Zeinab
