In data structures, I know that the size of the structure depends on the internal links from one section to another. Is there a way, aside from JProfiler to tell exactly how much memory is tied up in a particular structure?
For example, the class project this semester has to do with applying various structures to a song database. The projects have covered arrays, lists, unrolled lists and trees. What I would like to do is see how much memory is used. For example, a linked list has a memory requirement of 3N, but I would like to see how much space a node is taking up in my project.
JProfiler looks like it would work, but $500 is out of my price range, and I would like to use it for all the structures covered this semester, not the three applied so far.
Use VisualVM. It comes with the JDK and allows you to take a snapshot of the heap.
