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 memory in it's heap between steps 2 & 4. so that one can assume that whatsoever output comes belongs to my object. I am at something better.
Jim you are absolutely right, this technique may return a negative number.

The first one looks promising.

hi,
I use SAX parser to load an LDIF file into memory. Whatsoever data i read, i fill into an object.
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 Card String filename; long lastLoadedTime; }
public class Card{ String name; String email String mobile; }
