Is there a way I can check the memory size allocated to a JVM?

See the Runtime class, freeMemory(), maxMemory() & totalMemory() methods.
Note that the totalMemory() value will generally not match what is shown
by operating system utilities such as the Windows task manager or the *nix
ps command. I think that is based on the amount of memory that the JVM
has malloc'd, and does not include code space, static data, etc.
