Dharam,

Please change your name to be compliant with JavaRanch's naming policy.
Your displayed name should be 2 separate names with more than 1 letter each. We really would prefer that you use your REAL name.
Thanks,
Cindy

I would write it to a temporary file, then use the File length() method.

Your method can do the estimation, but not accurate. There is no way to accurately measure the size of object in Java as C sizeof() method. I guess that is intentional to hide some poor memory management problem in Java. Another thing is different JVM can have different implementation as well as different sizes.
