You can't.  That is one of the reasons behind the primitive type Wrapper
classes such as Integer, Boolean, Float.  Vector can only contain
objects.

To load a Vector with int values:

Vector t_vector = new Vector(5);

for (int idx = 1; idx <= 5; idx++) {
   t_vector.addElement(new Integer(idx));
}

To turn around and dump the Vector:

int t_vectorSize = t_vector.size();

for (int idx = 0; idx < t_vectorSize; idx++) {
   System.out.println((Integer)t_vector.elementAt(idx));
}

Remember, Vectors are like arrays, they start at zero not 1.
