Hey this is my first time posting so i am not really sure what the rules are but maybe someone can help me here, I am trying to do the drill and practice at the end of Chapter 6 which works on the Bubble scenario and for some reason i am stuck on Exercise 6.28, it calls for making a private method for the world called setup and naturally i attempt the import greenfoot.*; // (World, Actor, GreenfootImage, Greenfoot and MouseInfo) import java.awt.Color; /** * A bit of empty space for bubbles to float in. * * @author Michael Kölling * @version 1.0 */ public class Space extends World { /** * Create Space. Make it black. */ public Space() { super(900, 600, 1); getBackground().setColor(Color.BLACK); getBackground().fill(); } private int setup() } does not work either, is their something i am missing?

Calling a method from within itself is not something you should do without great care (as coded above, the calling of the method will continue indefinitely, causing the project to throw an exception); anyway, Super_Hippo said to call the method from the constructor -- not from the method itself.
