See http://mindprod.com/applet/fileio.html

It will generate you code to do this.  Make sure you ask for buffered
if you want speed.

Get rid of Float objects and just use pure float primitives if you
want speed.

There is not much overhead, just flipping the little endian Intel uses
internally  to big endian.

For me, the appeal of computer programming is that
even though I am quite a klutz,
I can still produce something, in a sense
perfect, because the computer gives me as many
chances as I please to get it right.
