import greenfoot.*;
 
public class BubbleGun extends Actor
{
    protected GreenfootImage bubbleImage = new GreenfootImage("bubble.png");
    private boolean spaceDown = false;
     
    public void act() {
        // shooting
        if (spaceDown != Greenfoot.isKeyDown("space")) {
            spaceDown = !spaceDown;
            if (spaceDown) {
                Bubble bubble = new Bubble();
                getWorld().addObject(bubble, getX()+0, getY()+0); // adjust offsets ass needed
            }
        }
 
       /**  other gun actions here  */
    }
     
    private class Bubble extends Actor
    {
        protected void addedToWorld(World world) {
            setRotation(BubbleGun.this.getRotation());
            setImage(bubbleImage);
        }
         
        public void act() {
            move(5);
        }
    }
}
and ... yes, one class is within the other as shown. Each Bubble object belongs to a specific BubbleGun object.
