Checking the heap size of a jvm at run time

[iris]

Hi,

After using the java run options -ms64m -mx64m that sets the heap size
of a run to the number specified, i would like to check what the
actual value of the heap size is at run time.
Does anyone know how to verify that?

Thanks!
Iris.

Either from java:
Runtime.getMaxMemory, Runtime.freeMemory or Runtime.totalMemory
or use a profiler like jmp (http://www.khelekore.org/jmp/) that
can show the current heap size (and lots of other things).
