How to see memory utilisation of user java classes?

I want to analyse the memory consumption on the basis of different class files, other than the java provided classes (String,etc). I tried JProfiler, jmap and jhat - all provide the information about java classes, but nothing about the custom classes.

Is there any way to see the memory utilisation of the classes which I have written in the web application?

The heap walker in JProfiler shows you this information:

enter image description here

after you click the "calculate estimated retained sizes" link above the table. The result is shown in the "Retained Size" column.

Yourkit has excellent memory telemetry where you can analyze class level memory. https://www.yourkit.com/docs/java/help/memory_telemetry.jsp

JVisualVM has also memory snapshot for class level but not as good as Yourkit. https://visualvm.java.net/snapshots.html
