what to use?

i'm new to java and wanted a help. i have a set of strings, which needs to be mapped to a integer value. i should be able to retreive the integer when given the string.
would hashmaps be the best suggestion for this?

Note that the mapping Hash(String) -> int is a surjection, i.e. for two different
string S1 != S2 it is possible that Hash(S1) == Hash(S2). On the other hand
if S1 == S2, Hash(S1) == Hash(S2) as well.

kind regards,
