getWorld().addObject(new NameOfTheClass(), x, y); // x and y are the coordinates where it should be spawned

My concern is what class the code given is in and what type of actor is being spawned. Often new coders misplace where code should go and I wonder if that is the case here. Maybe supply a little background as to what these actors are for and what they are supposed to be doing.

it is in the actor class and i was going to write the method then call it in the same class.

it didn't work (and its not because the spawning number was not randomly generated because i changed it to 0-1 and put if it equals one and it still didnt work)

Do you have 'Greenfoot.getRandomNumber(1)' or 'Greenfoot.getRandomNumber(2)'?

I could already tell it was in an actor class. I still would like to verify that you are doing things properly.

Okay -- you are spawning enemies; but, from what class? Why are you spawning them from an Actor subclass?

because enemies come from different directions and need to spawn in a different place from the other enemies. enemy1 spawns in the north, enemy2 in the east side, and so on.

i thought to have the corresponding code in its respective actor would be easier; just copy and paste it and change the names

Please show an example class.

I think you are spawning Actors for an actor which is bad. you should use something like this: 
addObject(new NameOfTheClass(),Greenfoot.getRandomNumber(getWidth()),Greenfoot.getRandomNumber(getHeight()));
in the world if you only want enemies spawing for the corners you should use : 
addObject(new NameOfTheClass(),Greenfoot.getRandomNumber(2)*getWidth(),Greenfoot.getRandomNumber(2)*getHeight());
