Metrics or Performance or quality measuring Tools for Java

Question

Hi there!
I have transformed a legacy C application into an object-oriented one.
I am actually having two implementations of this code - one properly reengineered one (using design patterns), and the other one is merely language conversion (line-to-line conversion from c to java).
I am doing this for my project. I am trying to compare the two versions and highlight the advantages of reengineered one, and especially benifits of DP.
As a part of this - instead of me explaing the difference (from my point of view) verbally, I was hoping it would be nice if I have tool that quickly runs through the program and gives me a report on performance or quality or software metrics of the program. (I would be more than glad if the report is automatic, instead of me figuring it out - coz I don't much about metrics, etc).
Do U guys know any tool which will do this kind of performance or quality measuremnt ?? Especially the ones we can download for free or atleast for 30 days trial??
Any input on this will be really really helpful.
Thanks very much

Hi asquithea!
Thanks for your reply.
I had a brief look at the following together soft link
http://www.togethersoft.com/services/practical_guides/getting_started/10qualityassurance.html#metric
In the example, where it showed "generating project metrics" - it wasn't very descriptive (atleast for me).
It says something like this:
Fan out
Aggregation: maximum
limits lower upper
package 0 15
classes 0 15
Does aggregation mean something here?? I will be glad if you can help me figure out what's happening there.Thanks very much for your help.
