Spawn only if none are in the world?

Hello, I have some code here for my game. It spawns a random orb for random numbers. Sometimes it's great but sometimes it spawns multiple which are un-dodgable. Is there a way to make this code check if an orb is in the world already and if so don't spawn? 
    public void randomSpawn() {
        if (Greenfoot.getRandomNumber(80) > 78)
        {
            Orb orb = new Orb();
            addObject(orb,526,513);
        }
    }

    public void waitForSpawning() {
        if(waitTime > 1500)
        { 
            randomSpawn();
            waitTime = 0;//resets timer 
        }
        waitTime ++;//timer counts up
    }

The following will return 'true' if no Orb is in the world. You can use it as another if condition. 
getObjects(Orb.class).isEmpty()
