Is it possible to use a primitive type (int) in as a generic type in Java?
Question
Specifically, with a SortedMap<Vector<String>, int>
I get "dimensions expected after this (int
) token." Help!
Solution
No, this is not possible. Use Integer
instead. Autoboxing takes care of the rest (i.e. for most purposes you can program as if you had actually used int
because Java converts to and from Integer
automatically for you).
OTHER TIPS
Konrad is correct. Alternately, you can use the trove class TObjectIntHashMap to map Objects to primitive ints.
