perfomance test: heap vs. swap space

I've launched some perfomance test for some program measuring
number of operations, net messages processed per second, etc.

Why is my point, is the question how Java initial and maximal
heap is connected with the swap space of Operating System.
Those Java utilize both memory and swap space for purpose
of its heap?

TIA,

Please read you OS book!

Isn't swap space supposed to be transparent to programs?
Isn't the JVM another program?
