Question

I need help getting my game to select a random plant to paint here is the code for Actor and the two plants and the paintComponent that paints the objects. If you need anything else please comment and I can add it. The comments in paintComponent is where and what I think I need to change.

package ale import java.awt.geom. Point2D public class Plant extends Actor e public Plant ( Point 2D . Double startingPosition, Point2D·Double initHit box, Buffered Image img, int health, int cooLDown, int super(startingPosition, initHitbox, img, health, cooLDown,0, attackDamage) An attack means the two hotboxes are overlapping and the Actor is ready to attack again (based on its cooldown) *Plants only attack Zombies * @param other e Override public void attack(Actor other) if (other instanceof Zombie) super.attack(other) 1 public Example) super); // TODO Auto-generated constructor stub 4 // Define some quantities of the scene numRows - 5; numCols- 7; cellSize-75; setPreferredSize(new Dimension (50 numCols cellSize, 50 numRows * cellSize)) rand-new Random); ranPicturenew Random(); // Store all the plants and zombies in here. actorsnew ArrayList

public void paintComponent(Graphics g) {
        
        super.paintComponent(g);
        
        ArrayList<Actor> plants = new ArrayList<>();
        
        for(Actor actor: actors) {
                if(!(actor instanceof Zombie)) {
                        plants.add(actor);
                }
        }
        
        // now you have only plants.
        int index = (int)(Math.random() * (plants.size()));
        
        Actor p = plants.get(index);
        p.draw(g, 0);
        p.drawHealthBar(g);
}
