Randomizing shot

Processing Coding Questions
1

I’m trying to design an enemy that shoots multiple shots in random directions, I have an Idea of what I want to do, but I don’t know where to put it. What I want to do is make the xSpeed of the shot randomize between 0 and 12, and then take that amount and subtract it from 12 to get the ySpeed. All of the code related to it is here:

abstract class Projectile extends GameObject
{
  Projectile(float x, float y, float w, float h, float xSpeed, float ySpeed)
  {
    super(x, y, w, h);
    this.xSpeed = xSpeed;
    this.ySpeed = ySpeed;
  }
}

abstract class EnemyProjectile extends Projectile
{
  EnemyProjectile(float x, float y, float w, float h, float xSpeed, float ySpeed)
  {
    super(x, y, w, h, xSpeed, ySpeed);
  }

  void reactions()
  {
    for (int x = 0; x < collisions.size (); x++)
    {
      GameObject o = collisions.get(x);
      if (o instanceof Player)
      {
        die();
      }
      if (x<0 || x > width || y < 0 || y > height)
      {
        die();
      }
    }
  }
  void act()
  {
    super.act();
    if (x<0 || x > width || y < 0 || y > height)
    {
      die();
    }
  }
} 

class RandomShot extends EnemyProjectile
{
  RandomShot(float x, float y)
  {
    super(x, y, redShot.width, redShot.height, 0, RED_SHOT_SPEED);
    image = redShot;
    damage = RED_SHOT_DAMAGE;
  }
}

if (timer > EVIL_SQUARE_COOLDOWN)
    {
      objects.add(new RandomShot(x + (image.width/2), y + image.height));  
      timer = 0;
    }

When the shooting happens by adding x2 and y2 to the bullet position :

x2=random(-6,6);
y2=random(-6,6);
