That's what I guessed too, but I should have really said the object will be
of class FileInputStream - but that still makes little difference in trying

Simply use your own objects that are FileInputStreams to
support this behavior.

public class NameableFileInputStream extends FileInputStream {
   String   savedName = null;
   public NameableFileInputStream(String name) {
      super(name);
      savedName = name;
   }
   public String getName() {
      return savedName;
   }
   public static String getName(InputStream obj) {
      String name = null;
      if (obj instanceof NameableFileInputStream) {
         NameableFileInputStream nObj = (NameableFileInputStream)obj;
         return nObj.getName();
      }
      // Or null, or whatever you feel is appropriate
      return "unknown - " + obj.getClass().getName();
   }
}

...Later, where the code needs the name....
name = NameableFileInputStream.getName(inputStream);




In every single ethnic, religious or racial group, there are a
very few truly evil people. For each of those people there
are many, many, many good people.
Assuming anything (evilness or capability for evil) about the
particular group is bigotry and idiocy. Don't do it.  -- Me
