    No, primitives are not objects. Yet, if you need an object (for example to
    put it in a hashtable or something) you can do the following:

    int i = 3;
    Integer object_i = new Integer(i);

    now you have an object and you can do

    System.out.println(object_i.getClass());

    Every primitive type has it's own corresponding object type.
    int -> Integer, double -> Double, etc.

    See documentation on this classes.
