title: Java File I/O problems
body: <p>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. </p>
  
  <p>Whne I try to write to a file <code>public static OutputStream...</code> errors out as an <code>illegal start to expression</code>, and I've been unable to get the program to step through an entire directory of files instead of one at a time. </p>
  
  <p>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?</p>
