Is there a way to randomly add actors at random points along the edges of the world?

Actor actor = new EdgeActor();
int x = Greenfoot.getRandomNumber(getWidth()); // random x (possible)
int y = Greenfoot.getRandomNumber(getHeight()); // random y (possible)
if (Greenfoot.getRandomNumber(2) == 0) // which edge to be on
{
    x = (getWidth()-Greenfoot.getRandomNumber(2))%getWidth(); // random edge (left or right)
}
else
{
    y = (getHeight()-Greenfoot.getRandomNumber(2))%getHeight(); // ranom edge (top or bottom)
}
addObject(actor, x, y);

Do you write that code in the world class?

Yes, in the constructor to be specific.

The code given was written as if in the world class. Whether it should go in your constructor or not depends on whether you are setting up your world (then, yes, constructor) or you are providing game play behavior (then, act method or a method it calls).
