. If the content is a file (or analogous to a file), then the file is removed from its directory (or container). If the content is a directory (or analogous to a directory), then the directory is removed only if it is empty (i.e. contains no other files or directories).
The default implementation does nothing.

. If the file does not exist, the file should be created. If the directory path to the file does not exist, all necessary directories should be created.
The default implementation attempts to open the OutputStream
through the URLConnection

. If the URLConnection
implementation does not support an OutputStream
then an UnknownServiceException
(a runtime exception) will be thrown.
