Scanneritself has no way to rewind the input. You might be able toreset()the underlying input stream, but that might not be supported depending on what stream implementation is being used. Your best bet is to close and reopen the input.EDIT:
If you cannot close/reopen the input, then try calling
reset()on the underlying stream.
