Hello, I have a method for spawning "Rocks" which looks like this:

public void placeRocksBeginning()
    {
       for (int i = 0; i < 25; i++) 
       {
          int x = Greenfoot.getRandomNumber(900);
          int y = Greenfoot.getRandomNumber(900);
          addObject (new Rock(), x , y);
       }

How can i set a rotation for the rocks?

How exactly do you want to rotate them? Do you want to rotate them while they are falling or should they just have one random rotation angle?

Rock rock = new Rock();
rock.setRotation(90);
addObject(rock,x,y);

They just should have a random rotation angle

I do not see any randomness in the rotation of the rocks.

No problem, i just changed it a bit:

public void placeRocksBeginning()
    {
       for (int i = 0; i < 25; i++) 
       {
          int x = Greenfoot.getRandomNumber(900);
          int y = Greenfoot.getRandomNumber(900);
          Rock rock = new Rock();
          rock.setRotation(Greenfoot.getRandomNumber(360));
          addObject(rock,x,y);
       }
    }
