Hi Nelson,

When I read a posting like this, I always think: 
"I guess somebody mailed him already."

and I don't help you out futher.

I think you would be better of just waiting for a response in the group you 
posted in.
In that way usenet has also use for others..

Regards,
Erwin

   A Vector is a simple expandable stack like array which has
synchronized accessor methods(thread safe, but slows you down some if
you do not need them, so the current best practice is to use ArrayList
if you do not need the synchonization)
Check out Sun's official documentation for more information:
http://java.sun.com/j2se/1.4.2/docs/api/java/util/Vector.html

Here is a simple explained use of a Vector

Vector v1 = new Vector();
v1.add("First Element");  //adds a string to the list, can be any
Object
v1.add("Second Element"); //add another string
v1.add(new Integer(5)); // add an integer in the Integer primitive
wrapper

/*with some elements in the Vector you can check for presence of
elements, or
get them at their index(like an array[]), get an itterator to traverse
the list, clear the list, etc.
*/
int lengthOfVector = v1.size();
boolean bVectorContainsElement = v1.contains("First Element"); // true
boolean bFalse = v1.contains(5); // exception needs to be an object
and will not compile
boolean bTrue = v1.contains(Integer(5));

String elementOne = (String)v1.get(0);
// clear the list
v1.clear();
