How does Java VM allocate memory?

Question

I am wondering how does Java VM allocate memory? does JAVA allocate memory in the physical memory in our computer? Right now I am trying to compare two data structures, linked list and array taking caution in terms of page fault, and cache hit/miss, to see the performance of each data structure in really low level(harddisk, memory, cache level)

Answer 1

I don't know if this answers your question but IBM has a good article about how JVM uses native memory on Windows / Linux.
