Use MidiSystem.getSequence() to create a Sequence from the File.
From the Sequence object, use getTracks() to extract the constituent tracks.
Then you can extract the individual MidiEvents from each track (using
get()), and analyse them to extract information about the notes, etc.

See the javax.sound.midi API docs for details.
