I'm getting this error on a game I am designing for my ArrayList debris (the highlighted line is underlined and made bold in the code below). Specifically, the error says IndexOutOfBoundsException: index 2, Size: 2. I'm having trouble spotting the problem, perhaps someone else can help me? The code is below (the relevant code from what I can gather):

If you think more code is needed to resolve this issue just say so.

ArrayList debris;

void setup() {
  size(800,800);
  smooth();
  background(255);
   //Initializing all the elements of the array
  for (int i = 0; i < comets.length; i++) {
    comets[i] = new Comet();
  }
 
  score = 0;
  img = loadImage("space.jpg");
 
  debris = new ArrayList();
 
  tp = 2;
}


void draw()
{
  //Creating random Debris
 float randomNumber = random(0, 15);
 if((int)randomNumber == 1)
  {
      debris.add(new Debris(tp));
  }
 
 for(int i = 0; i < debris.size(); i++)
  {
    Debris d = (Debris) debris.get(i);
    d.update();
    d.display();
   
    //Debris collision
    for(int c = 0; c < comets.length; c++)
    {
      if(dist(comets[c].location.x, comets[c].location.y, d.location.x, d.location.y) <= 20)
      {
        //println("Debris Destroyed");
        debris.remove(i);
        score = score + 25;
      }
    }
   
    //Game over method
    if(dist(d.location.x, d.location.y, width/2, height/2) <= 20)
    {
      println("Game Over");
      println("Final Score: " + (score + frameCount));
      //println("Game Reset");
      //setup();
      noLoop();
    }
   
    //Increase speed as game goes on
   
    if(frameCount % 500 == 0)
    {
      d.topspeed = d.topspeed + 1;
      tp = (int)d.topspeed;
      //println(tp);
    }
    
}
