Hi there!

I am new to Java and I am currently working on an imlementation of an algorithm that requires the implementation of a hash tree structure.

I saw the java library and I was wondering how to implement it by extending Tree or HashMap, but I can't decide on either one of them.

For starters, could someone explain to me a liitle about how a Hash Tree works, and what I need to have in mind to imlement it? If you have a link that explains it, it's also ok. I have googled a lot already but I haven't found something really good...

//also if you were to implement it, which java classes would you extend?
//I am also new to this forum, so if the post is out of place, I apologize in advance
