This is my first time working with file i/o in java, and it's not working. The section of the program where I parse individual lines and output a semicolon delimited line works like a charm when I hardcode a file and display on screen.

Whne I try to write to a file public static OutputStream... errors out as an illegal start to expression, and I've been unable to get the program to step through an entire directory of files instead of one at a time.

Where I'm not clear: I'm note setting an output filename anywhere...whare am I supposed to do that? The path variable won't pass. What's the proper format for a path? Can anyone see what I need to debug here?
