which collection prefered?

[Alex Leung]

Hi, I have done some research on which collection looks possible for handling the implemnetation of this assignment, while I do think Vector is capable of doing the job, Hashmap seems to be better because it uses keys, but I could use the Vector index as key implemnetation as well.
Collection.synchronizedMap/Set can be use on Hashmap and set. Other collections like Hashtable and Hashset also provide simliar functionalities too.
Personally I think I perfered Hashmap, but any advices or suggestion?
Thank you

First it is preferred to use ArrayList and HashMap over Vector and HashTable. The first two are considered the newer Collection classes. As far as all the others, it really depends on what you want to store and how. When you know that the choice becomes easy, because there is one and only One Collection that handles exactly that. Sort of.
