Get a set of coordinates between two points?

What I have so far is:

public static List<String> getIds(int x, int y, int range) {

    int ax = x+range;
    int ay = y+range;

    int bx = x-range;
    int by = y-range;

    System.out.println(Point2D.distance(ax, ay, bx, by));

    // get all coordinates between those two points above.
    // and add them to the string array like "x,y";

    return null;
}

I used the Point2D.distance to make sure the range was right, but for this method I need to get all the coordinates (integers not doubles) between [ax,ay] and [bx,by] yet I cannot find any utility methods within Point2D which does this.

If you want all the points, you'd need nested loops like :

for (int i = -range; i <= range; i++) {
    for (int j = -range; j <= range; j++) {
        System.out.println(String.format("(%d,%d)", x+i, y+j));
    }
}
