this might seem stupid, but I was wondering if there was any way to get a random subclass? like, say i had a subclass of actor and then 3 subclasses of that subclass, and i wanted to select a random one of those 3 to display on the screen. is that possible? like how there's Greenfoot.getRandomNumber(), but for subclasses?

Here is an example method using mock class names. The return type can be modified to be the parent class name. 
private ParentClassName getRandomParentClassNameActor() {
    ParentClassName actor = null;
    switch(Greenfoot.getRandomNumber(3)) {
        case 0:  actor = new SubclassA(); break;
        case 1:  actor = new SubclassB(); break;
        case 2:  actor = new SubclassC(); break;
    }
    return actor;
 }
