Java remove objects

Question

I have a world that is the GameScreen (20ish objects) which lays all objects as intended. However, when I get GameOver I want to be a blank canvas with just the background and some new objects(a couple objects), but all the existing objects from GameScreen carry over and I cant figure out how to stop it or delete them on the GameOver screen

public class GameScreen extends World
{
    public GameScreen()
    {
      super(600, 400, 1); 
      prepare();
    }

    private void prepare()
    {
      addObjects.......
    }
}


public class GameLost extends GameScreen
{  
    public GameLost()
    {
      removeObjects(GameScreen);
      prepare();
    }

    private void prepare()
    {
      addObjects...
     }

This question is too broad, what do want to remove and what do you want to keep? — Stephan Hogenboom, Dec 05 '18 at 14:13
@stephan-hogenboom I reworded the question. I want to remove the objects that carry over from GameScreen to GameOver. I only want GameOver to keep the same background and not any of the objects. — Ryan W, Dec 05 '18 at 14:18

I'm pretty sure you don't want GameLost extends GameScreen.

Do

class GameLost {
   private Background bg;
   public void paint() {
       paint(bg);
   }
}
class GameScreen {
   private Background bg;
   private List<GameObjects>...
   public void paint() {
       paint(bg);
       gameObjects.forEach(go -> paint(go));
   }
}

which makes it easy to move over the background from game screen to game over screen, without the game objects.
