ISortable

[Me]

I have a class called Page that contains 2 members, TextObjectArray and
ImageObjectArray as follows:

public class Page
{
public Page(int pageN)
{
//
// TODO: Add constructor lmilogic here
//
pageNumber = pageN;
}

private int pageNumber;
private ArrayList textObjectsArray;
private ArrayList imageObjectsArray;
}

I'll need to come up with a method to sort both TextObjectArray and
ImageObjectArray. I was advised to use ISortable interface. Who can
advise me on how to implement the ISortable interface and to use it for
sorting TextObjectArray and ImageObjectArray? Thanks a bunch?

There's no standard ISortable interface. Perhaps you mean IComparable?
ArrayList.Sort will use IComparable if the item implements it (and you
don't specify another IComparer).

Thanks Mattias! IComparable is the right answer!
