Storing set of values in an array

Question

I am curious how this would be done best. I have 15 sets of x and y values, that should be stored together. I was thinking I could have an array, holding 15 other arrays, each holding the x and y value? Is that a valid way to do this? Also, is there a way to create those arrays holding the x and y, dynamically, so they just get numbered?
MainArray[
     subArray[x1, y1];
     subArray[x2, y2];
     subArray[x3, y3];
     subArray[x4, y4];
     subArray[x5, y5];
     subArray[x6, y6];
     subArray[x7, y7];
     etc...
Obviously, above is not correct AS. Is this even a way to do this? Are there other much better ways???
Thanks a lot!

Answer 1

In addition to Ned's suggestion you can use points:
var array:Array = [new Point(100, 50), new Point(40, 30), etc.]
You would read/write it the same way as in Ned's example:
array[1].x
array[1].y
Although Ned's suggestion is more compact, if you need to use Point class' properties and methods that may save some calculations (especially if the array intended to use in some physics engine) - holding x/y in point instance is probably more desirable.
