IOException error

edited September 13 in Using Processing

I trying to make a reader but i get a error (Unhandled exception type IOException)

BufferedReader reader; String line; void setup() { // Open the file from the createWriter() example reader = createReader("positions.txt");
} void draw() { try { line = reader.readLine(); } catch (IOException e) { e.printStackTrace(); line = null; } if (line == null) { // Stop reading because of an error or file is empty noLoop();
reader.close(); } else { String[] pieces = split(line, TAB); int x = int(pieces[0]); int y = int(pieces[1]); point(x, y); } }

does any one know how i can let it work?
