Class-wise profiling of Java memory consumption -

-

i have java project initializes thousands of objects in tree-like hierarchy.

initially, programming performance in mind , didn't mind storing lot of computable properties in class fields(variables)..
however, recently, started trying estimate memory footprint of project , found large.

i'm trying identify class consumes memory
guess can narrow down field consuming (probably strings)

i have come across java's instrumentation package , getobjectsize

i tried understanding documentation, i'm not sure if instrumentation suited task.
have noticed getobjectsize not recursively find sizes.

i thinking of creating class extends object , contains static map of instance -> instancesize, , making classes extend class , updating constructors

is approach correct?
'java' way of accomplishing this?

um, put down coding tools , pick memory profiler. there great free ones out there.
