You were spot on!
This results from perhaps a slight misunderstanding of java itself.
Because List is an interface.. and you can't create Objects of that
type.. I thought List temp.. etc wouldn't be allowed.
As indeed, List temp=new List(); wouldn't be allowed...
but doing the above solved my problem.. and now I assume if the return
type is a List.. you can do List temp = <thing that returns the List>
So not only have I learned some jdom, but also some java.. many thanks!!
(only been learning Java 8 months .. long enough that I should have
known this.. but...)
p.s. My project now works.. and I managed to compress a 76 byte (tags
only, no content) xml file into a 2 byte file.
And more importantly managed to decompress it back to the original data.
Thanks a lot to everyone for their help!!

would improve man, but it would deteriorate the cat.
