Any Java hash tree implementations?

Question

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?
