What is the difference between HashMap and HashSet?

Answer 1

Find more info here:

http://stackoverflow.com/questions/2773824/difference-between-hashset-and-hashmap

This is the clearest answer I found there:

"
HashSet is a set, e.g. {1,2,3,4,5}

HashMap is a key -> value (key to value) map, e.g. {a -> 1, b -> 2, c -> 2, d -> 1}"

Answer 2

hashmap is used to create and search in a map, however hashset is used while storing the keys and values in a map, thats all
