For library code, the template is in $JDK/make/templates/gpl-cp-header [1].
It begins:

  Copyright (c) %YEARS% Oracle and/or its affiliates. All rights reserved.

  This code is free software; you can redistribute it and/or modify it
  under the terms of the GNU General Public License version 2 only, as

You can just use the Oracle copyright line or, at your option, replace
it with your own.  In any case %YEARS% should be replaced with the year
in which the file was created, and if it was modified in any later year
then the creation year should be followed by the latest year in which
the file was modified, separated by a comma.

(We can better advise you on the details once we see the actual code.)
