Need tutorial on Hashes

Hi All, I need a good tutorial on HashCode, Hashmap, Hashtable and Map. My concept about all those are not clear (specially how the bucket concept is helping us to avoid collision). Is there any good (with graphical explanation) tutorial available out there or published by JavaRanch?

Thanks
