Hi all
I'm facing a weird problem with for loop , here is my code



this is the output



you will find my questions as comments in the code and the output . what i wanna do is when i = 0 it goes to the inner for loop till x reaches 28 then increment i by ...etc till i reaches 13 ..

Any thing i was missing ?

Happy new year to all

You're printing to two different print streams that aren't synchronized -- System.err and System.out. Why?

Because there is no element at position x for that list. I'd also split out your code a little so that you can clearly see when you are accessing what.

Because either the inner or outer vector used in vBckTableTotal is empty, and so doesn't have an index 0.
