What has to happen is you need a Class.forName or however you are trying to load the class into the clasloader. Then afterward you instanstiate an Array of that class type by using java.lang.reflect.Array.newInstance(class, x) where x is your dimensions. So to answer your question it uses a java.lang.Class.
