Storing Coordinates as integers in a Vector or ArrayList??

Question

Greetings all,
I am trying to store a set of (x,y) coordinates in either a vector or an arraylist but don't really know which one is better or really the proper way to be doing it ... from my understanding firstly these numbers are stored as objects rather than integers, but i need them as integers because i would like to plug them into equations etc., from my understanding of vectors the code is something like this:
Vector v = new Vector();
v.addElement(0);
v.addElement(1);
v.addElement(2);
v.addElement(3);which results in a vector like v=[0,1,2,3] which if i'm not mistaken are objects not integers, but what if i want a vector which stores numbers as v=[(0,0), (1,0), (2,0), (3,0)] that are integers?
Your help is much appreciated.
Thanks.

Take the collections tutorial: [http://java.sun.com/docs/books/tutorial/collections/index.html]
Prefer collections framework classes like ArrayList over older legacy classes like Vector.
demo:
import java.awt.Point;
import java.util.*;
public class ListExample {
    public static void main(String[] args) {
        List<Point> points = new ArrayList<Point>();
        points.add(new Point(1,2));
        points.add(new Point(5,3));
        System.out.println(points);
}
