hi,
Thanks for the link but this is very naive way of doing it. I am leaving
it to the mercy of gc.
What this method is doing
1. run gc() manually (AND hope it wont run automatically again soon.)
2. free memory
3. create and object.
4. free memory
and now just wish that JVM wont allocate any memo
Whoops.. that should the problem with the first one on the list.. :)
I know Bad code monkey no caffeine.

I need to know *the size of LDIFData object* at runtime. How to do that?
Well the class structure is something like this
public class LDIFData{
ArrayList cards; // collection of C
15 matches
