size of an object

[pradeepta chopra]

how do we find out the size of an object?
somewhere i read that the way is to convert into string and note the length.
but i find a string like @1fee6fc???
now wat does the above string represent??

It's a bit more involved than that, I'm affraid.
Take a look at this Javaworld article.

The "@1fee6fc" that you see when you call the toString() method of class Object is the hash code of the object in hexadecimal; it does not have anything to do with the size of the object in memory (or the address of the object, as some people think it is).

There is no easy way to find the size of a Java object in memory.
