I am writing a program using writer, and everytime i try to run the program it says Type "writer" was not found. Currently I am just using the example straight from the site to test it.  Can anyone help me?

PrintWriter output;

void setup() {
 output = new writer("positions.txt"); // Create a new file in the sketch directory
}

void draw() {
 point(mouseX, mouseY);
 output.println(mouseX); // Write the coordinate to the file
}

void keyPressed() {
 output.flush(); // Writes the remaining data to the file
 output.close(); // Finishes the file
 exit(); // Stops the program
}

oh, new Processing versions seem to have createWriter instead of writer, see here:

so the code should be:

output = createWriter("positions.txt");
