Adding array to array list

There is a command vertex, therefore it’s confusing to name your ArrayList vertex

better would be vertexList.

You could say

before setup():

ArrayList<PVector> vertexList = new ArrayList();

in setup():

vertexList.add(new PVector(x+w/2*sin(thetac), 
  y+w/2*cos(theta*c)));
