There is an incredibly arcane sequence of stream creations
that Java makes you jump through to do the equivalent of
fopen() and fprintf(). I have to re-find the last piece of
code that I wrote and copy it every time I need it.
OK I found it (again):
PrintStream out =
new PrintStream(
new BufferedOutputStream(
new FileOutputStream( new File( "file.txt" ) )), false );
out.println( "whew" );
At least readline() type input is a bit easier:
BufferedReader in =
new BufferedReader( new FileReader( "file.txt" ) );
String got = instr.readLine();
One day I will put these someplace that I remember where they are,
but by then I will probably have forgotten what they are for...

Hi,
Thanks for the help. I am planning to take the byte array and then write
it to file using java i/o or may be to a database according to motes
address. I don't understand what you meant by- work out the sequence of
stream opens needed to use Java file i/o directly.
Thank you

You should be able to modify Listen.java to dump the data in any
format you like. You can then just redirect it's output to a file

or for extra credit work out the sequence of stream opens needed
to use Java file i/o directly.
