Use java WavFile to read in wav file

[Make42]

I would like to use your java WavFile to read in a wav file and turns its channels into a nested ArrayList as in

java.util.List[java.util.List[Double]]

where each Double is a value from the wav file and java.util.List[Double] is a channel of the wav file. Can you give an example how to do this, considering my file is "path/to/file.wav"?
