Create a new Formatter.
If you look at the constructors for Formatter, you will see that its
mission in life is to dump data to some stream-like object, be that a
literal stream, or a File, or any sort of Appendable object. As such, it
is aimed at calling format() multiple times to dump more data to the
same output stream, then closing up the stream (via flush() and close()).
If you want to dump data to some new stream (in your case, a new
String), you need to create a new Formatter.
