Simply put: That's because arrays are covariant. Let's extend your example: Object[] objArray = array; This one's OK, ArrayList<String> is a subtype of Object, therefore, ArrayList<String>[] is a subtype of Object[]. ArrayList<Integer> intList = new ArrayList<Integer>(); intList.add(42); objArray[0] = intList; Still OK ... String s = array[0].get(0); => ClassCastException. For this reason, it's not possible to use generic arrays in Java. cu, Raffi -- The difference between theory and practice is that in theory, there is no difference, but in practice, there is.
