Is this possible?

For example, assuming that I serialized this class

import java.io.*;

public class StorageClass implements Serializable {

        private static final long serialVersionUID = 1L;

        public Serializable[] stored;

}

I then set the stored array to a set of serializable objects.

At a later time, I want to deserialize the object, but one of the
stored classes is no longer available.  Is there a way to deserialize
the object, but have that entry in the array be null?
