I'm pretty new to programming and I feel like there's something obvious that I'm missing. I have an ArrayList filled with PVectors, and I'd like to use use those coordinates to draw a point for each PVector. How do I translate the coordinates stored in the PVectors to the parameters of a point? Or in other words, how do I display my ArrayList of PVectors as a series of points?
Here's my code:

1. PVector myPos;
   ArrayList myPoints = new ArrayList();
   
   void setup() {
     size(300, 300,P3D);
     background(255);
     byte b[] = loadBytes("portcus.txt");
     // Print each value, from 0 to 255
     for (int i = 0; i < b.length; i++) {
       // Every tenth number, start a new line
       if ((i % 10) == 0) {
         println();
       }
   
       if ((i % 2) == 0) { 
         // bytes are from -128 to 127, this converts to 0 to 255
         int x_ = b[i] & 0xff;
         int y_ = b[i+1] & 0xff;
         myPos = new PVector(x_, y_);
         myPoints.add(myPos);
         println(myPos.x + ", " + myPos.y);
       }
     }
     // Print a blank line at the end
     println();
   }
   
   void draw(){
   for(int i = 0; i< myPoints.size(); i++){
     //println(myPoints.get(i));
     //this for loop is where I was intending to draw the points
   }
   }
   

Currently all it does is coding a txt file as byte date, translating each letter in the file to a number between 0 and 255, storing the info in a ArrayList and then printing the values to the console. I was going to make two Arrays, one for the x coordinates and one for the ys, but my professor said this would be easier (And then he left to go help other students and this is as far as I got).
Any help is greatly appreciated~
