Hi all, I'm trying to split a stream of numbers into different text files using PrintWriter.  A simplified pseudo-code example:

1. // create a random number
   int randomNumber = int(random(0,10));
   PrintWriter output;
   
   // depending on what that number is, write to a different file
   if (randomNumber == 0) {
     output = createWriter("0.txt");
     output.println(randomNumber);
   }
   if (randomNumber == 1) {
     output = createWriter("1.txt");
     output.println(randomNumber);
   }
   
   output.flush();
   output.close();

It will write, but seems to overwrite the existing line... or something else wonky.  The Java docs show an "append" feature but it doesn't seem to work (and should println work anyway?)...

Suggestions?
