list - Java: Fastest structure to store and retrieve large number of strings -
i need create java structure store large number of string
. need add new strings , check if string present... order of strings not important.
i don't know many java datatypes typical list
, set
, map
, so... fastest datatype scenario? may treeset
or there other i'm missing?
it depends on kind of access need.
- sequential:
linkedlist<string>
- random:
arraylist<string>
- check presence:
hashset<string>
(this 1 looking according reqs) - check presence , sorted traversal:
treeset<string>
