Hey guys, I am in need of some help I have a game where my Alien isnt appearing and i cant figure out why. The main part of the problem is the last section of my code.  Any help would be much appreciated

class Bullet
{
  private PVector loc = new PVector();
  private float angle;
  private Cannon c;
  private int age = 0;
  PVector center;
  PVector turret;
  public Bullet(Cannon c, float x, float y)
  {
    this.c = c;
    loc.x = x;
    loc.y = y;
    center = new PVector(c.loc.x,c.loc.y);
    turret = new PVector(c.cX,c.cY);
  }
  void run()
  {
    noStroke();
    fill(200);
    ellipse(loc.x,loc.y,10,10);
    PVector vel = PVector.sub(turret,center);
    loc.add(new PVector(vel.x/15,vel.y/15));
    age++;
    if (age>100)  bullets.remove(this);
  }
}

class Cannon
{
  public PVector loc = new PVector();
  private float r = 90;
  float cX;
  float cY;
  public Cannon(float x, float y)
  {
    loc.x = x;
    loc.y = y;
  }
  void show()
  {
    smooth();
    float angle = atan2(mouseY-loc.y,mouseX-loc.x);
    cX = (r * cos(angle)) + loc.x;
    cY = (r * sin(angle)) + loc.y;
    fill(255,0,0);
    noStroke();
    ellipse(loc.x,loc.y,80,80);
    noFill();
    stroke(255,0,0);
    strokeWeight(20);
    line(loc.x,loc.y,cX,cY);
    fill(0,200,0);
    noStroke();
    ellipse(loc.x,loc.y,70,70);
    noFill();
