Name PrintWriter Examples PrintWriter output; void setup() { // Create a new file in the sketch directory output = createWriter("positions.txt"); } 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 } Description Allows characters to print to a text-output stream. A new PrintWriter object is created with the createWriter() function. For the file to be made correctly, it should be flushed and must be closed with its flush() and close() methods (see above example). Methods print() Adds data to the stream println() Adds data to the stream and starts a new line flush() Flushes the stream close() Closes the stream Usage Web & Application Related createWriter()
