Reading JVM memeory of active class?

[Jroyal]

Hi, I would like to read all the memeory address and what is kept in them by the JVM.

I dont know what this is called, and i cant seem to find any books or articles on this.

can anyone point me to a direction.

You can monitor total JVM memory usage by doing :

Runtime.getRuntime().freeMemory()

and

Runtime.getRuntime().totalMemory()

There are also ways to output JVM memory usage in finer detail by firing the JVM in debug modes.
This thread details some options :

that just gives me the details of what memeory (space) is being used, what i want is to find out what memeory location is a certain class puting its data in.

I.e. a 3rd party program say, a rss feeder, its download data of the net and displaying it on the screenw ithout saving the data, i want to know where this data is being held in the ram, the memeory location.

so that i can use c++ or c to read that data, of the memeory space.

Is there anyway of tracing where the class is holding this data, and if so what is this called.

Java does not do pointer arithmetic, whatever that means,
