I'm programming a game, in which you move the rocket with the mouse up and down, that means the x-coordinate is always the same. When you press space a laser shot should come out of the rocket. How can I get the y-coordinate of the rocket in the laser shot class?

Your laser shot doesn't need the rocket's location. The rocket should just spawn the shot at its location using getX and getY.

Answer this: when does the laser need the y-coordinate of the rocket ... and why does it need it at that time?

when i press space a moving laser appears. I did this with a method in the world class, that works well. The problem is, that I'm not able to set the y (now on 400) to the same value as the rocket is. 
 if ("space".equals(Greenfoot.getKey()))
        {
            Laser laser = new Laser();
            addObject(laser, 1288, 400);
        }

Put the code into the rocket's act method and you can do: 
addObject(new Laser(), getX(), getY());

thank you very much it worked! with this code: 
 if ("space".equals(Greenfoot.getKey()))
        {
            Laser laser = new Laser();
            getWorld().addObject(new Laser(), getX(), getY());
        }
