I want to implement an algorithm that needs to use a hash tree. What are some good, easy-to-understand Java hash tree implementations? Are there books, websites or PDFs on the Internet that give a good explanation on how a hash tree works and how I could implement it?
Yes, there's a Java implementation of hash tree here:

There's an explanation here:

I was reading the JNI spec and saw the reflection support methods section.
I don't quite understand what they are used for or what's the intended purpose. Since method ID is looked up using name and signature, don't we already have that information? And if we want to get more details, we can always write a java wrapper. So that cannot be the purpose I thought.

Does anyone could recommend a framework or a java api that could help me compare two files? I would to compare both and mark one as yellow where we have the differences, like Tortoise do as example.

I'm looking for a library that could help me to print the directory tree from the list of strings.
List
"/a/b/c/file1.txt"
"/a/b/c/file2.txt"
"/a/b/file3.jpg"
and so on...
You can try abego tree layout. It gives you a way to display trees. It doesn't appear to be well documented but it works well. Here is a link to how to use it. https://code.google.com/p/treelayout/

what is the best Java library for manipulating graphs (specifically, for social network analysis)? I've seen Jung, but I was wondering if you knew anything better (I don't need to visualize networks, only computation).
Thank you
I've found jgrapht pretty useful - it has all the major algorithms (e.g. Bellman-Ford, ...)
neo4j is the choice
And here is a video

I am looking for an implementation of the Rabin Hash Function in Java, Can anyone recommend a fast library?
Update:
I've just tested the library here.
It takes ~2200ms to hash 1mm random urls on my 2GHz processor.
This is certainly good enough for my needs, however I will test another library when I get a monent and post the results here.
Here's my Java implementation.
http://code.google.com/p/rabinfingerprint/
It also includes arbitrarily large irreducible polynomials (using BigIntegers).
I've not used it myself, but you can try the Rabin Hash Function project on Source Forge.
