 }
 }

this is my problem,

for (int i = 0; && i<f.al1.size(); i++){
 kmi.add(Math.round(f.al1.get(i) / ( f.al2.get(i) * f.al2.get(i)/ 10000) * 1000) / 1000);

, it doesn't work

I've added code tags to your posts which might encourage someone to take a look, but personally, if you don't take the 5 minutes to read DarrylBurke's links, I don't really want to take the 5 minutes to examine your code.

[zifkele]

I just took the wrong tag switches, but I read it and i got it, ok?

[Tolls]

What does "it doen't work" mean?
How is it not working?

[quad64bit]

Alright, fair enough. However, you still have not answered anyone -

it doesn't work

is not a question.

You haven't told us what values you expect, what values you get, and how they are wrong.
