     (long)theObject // Won't work, cant cast between

     (Long)theObject // Nope
      Long.parseLong(theObject) // Works for String
objects. Expects a String object parameter. 

Assuming you're using the Wrapper Classes for Long,
etc., you can assign the difference of these two
objects to a primitive type by:

      (ie.
       Long objLong = new Long(15);
       Integer objInt = new Integer(10);
 
       long lng = (long)(objLong.longValue() -
objInt.intValue());


I'm not sure if this answers your question.
