I have a game where I have a multitude of enemies and I would like to start a new round when all of the enemies are gone. I have thought of using an array and then removing them when they die. But I don't know if this would be the right approach or how to go about implementing it. My main question is how can I tell if all the enemies are dead(removed from the world)? Please help and Thank you!!

If the enemies are gone then the list returned from using 'getObjects(Enemy.class)' should be an empty list (or be of size zero). The List class has both a 'size' method as well as an 'isEmpty' method that can be used on the list: 
if (getObjects(Enemy.class).isEmpty())

// or
if (getObjects(Enemy.class).size() == 0)
