Save settings when closing

I have a lot sliders. I wont to save the slider position when I close the application. I'm trying stop() and destroy() but it seems that both don't will be called.

its stop.... like in this example...

Code:
int[] x = new int[0];
int[] y = new int[0];

void setup() 
{
  size(200, 200);
}

void draw() 
{
  background(204);
  stroke(0);
  noFill();
  beginShape();
  for (int i = 0; i < x.length; i++) {
    vertex(x[i], y[i]);
  }
  endShape();
  // Show the next segment to be added
  if (x.length >= 1) {
    stroke(255);
    line(mouseX, mouseY, x[x.length-1], y[x.length-1]);
  }
}

void mousePressed() { // Click to add a line segment
  x = append(x, mouseX);
  y = append(y, mouseY);
}

void stop() { // save when closing window
  String[] lines = new String[x.length];
  for (int i = 0; i < x.length; i++) {
    lines[i] = x[i] + "\t" + y[i];
  }
  saveStrings("lines.txt", lines);
 
}

Mhmm, it seems not to work in eclipse. Here is my function:

Code:

public void stop() {
		String words = "apple bear cat dog";
		String[] list = split(words, ' ');

		// now write the strings to a file, each on a separate line
		saveStrings("nouns.txt", list);
	}

i tested your little sketch. I had to add draw() to prevent it from writing the file imidiatly before closing but if i run this :

Code:
 void draw(){
  }
 
  void stop() {
		String words = "apple bear cat dog";
		String[] list = split(words, ' ');

		// now write the strings to a file, each on a separate line
		saveStrings("nouns.txt", list);
	}



everything works the way it should. Writing the file when closing the sketch.

Maybe it's an eclipse quirk.
