i found a code that used an array for adding actors to the world ( the original discuss) my question: does it somehow work with worlds instead of actors too?

You can have an array of World objects. Worlds are not actors and do not "work" similarly to each other. For what reason might you want to use an array of worlds?

I have some subclasses of MyWorld called Level_1 , Level_2 ... I wanted to write a method in my Actor that can set the Level:
 void setLevel( int index) {
        World a = new Level_1();
        World b = new Level_2();
        World c = new Level_3();
        World d = new Level_4();
        World e = new Level_5();
        
        World[] world = {a,b,c,d,e};
        Greenfoot.setWorld(world[index]);
    }
that is what I made so far... is there a better way? can you somehow do that with a list so that you don`t need th declare every World?

Better might be the following (so as not to have so many World objects in memory at one time): 
void setLevel(int index) {
    World w = null;
    switch (index)
    {
        case 0:  w = new Level_1(); break;
        case 1:  w = new Level_2(); break;
        case 2:  w = new Level_3(); break;
        case 3:  w = new Level_4(); break;
        case 4:  w = new Level_5(); break;
    }
    if (w != null) Greenfoot.setWorld(w);
}
