I have a problem with understanding who to optimize my code.  
Main idea of program of creating a words with dots.

```auto
ArrayList<PVector> edgeVertices = new ArrayList<PVector>();
ArrayList<PVector> Adding = new ArrayList<PVector>();
char[] word = new char[5];
PFont font;
PShape shape;
PVector max;
String fontPath;
char c;
int border = 0;
int distance = 10;
int adding_length =1;
void setup() {
  size(900, 300);
  background(51);
  fontPath = "arial.ttf"; // Path to font file "AvenirNextLTPro-Demi.otf" Comfortaa-Light.ttf
  word[0] = 't';
  word[1] = 'r';
  word[2] = 'a';
  word[3] = 'i';
  word[4] = 'n';
  for (int i = 0; i < word.length; i++) {
    c = word[i];
    font = createFont(fontPath, 166, true);
    shape = font.getShape(c);
    for (int j = 0; j < shape.getVertexCount(); j++) {
      edgeVertices.add(shape.getVertex(j));
    }
    max = new PVector(edgeVertices.get(0).x, edgeVertices.get(0).y + 165);
    stroke(255);
    strokeWeight(8);
    for (int j = 0; j < edgeVertices.size(); j++) {
      for (int k = 0; k < edgeVertices.size(); k++) {
        float di = edgeVertices.get(j).y - edgeVertices.get(k).y;
        if (di < 0) di*=-1;
        if (edgeVertices.get(j).x == edgeVertices.get(k).x && di > distance) {
          Adding.add(new PVector (edgeVertices.get(j).x, (edgeVertices.get(j).y < edgeVertices.get(k).y?edgeVertices.get(j).y:edgeVertices.get(k).y) + di/2));
          ++adding_length;
        }
      }
    }
    for (int k = 0;k < Adding.size()-1; k++) {
      edgeVertices.add(Adding.get(k));
    }
    for (PVector v : edgeVertices) {
      point(v.x + 25 + border, v.y + 165 );
      if (max.x < v.x) {
        max.x = v.x;
      }
    }

    border += max.x + 20;
    for (int k = shape.getVertexCount()-1; k > 0; k--) {
      edgeVertices.remove(shape.getVertex(k));
    }
    Adding = new ArrayList<PVector>();
  }
}
void draw() {
}

```

This program to work needs an arial font

Hello,

> shape = font.getShape©;

Please format your code as a courtesy to the community:  
[https://discourse.processing.org/faq#format-your-code](https://discourse.processing.org/faq#format-your-code)  
You can go back and edit it.

I am not looking at any long unformatted code these days.

Try to copy your code and paste into Processing to understand this request.

Thank you for helping with reorganizing my code.

This was running at close to 100% CPU!

I added a println() here and there:

`println(edgeVertices.size());`

`edgeVertices.size()` kept growing larger!

This tamed the beast:

```auto
for (int k = 0;k < Adding.size()-1; k++) 
  {
  //edgeVertices.add(Adding.get(k));
  }

```

That is all I can offer at the moment.

It’s a start!
