Why can you cast int[] to Object, but not to Object[]?

Question

So this works:

int i;
Object a  = (Object) i;
int[] t;
Object b = (Object) t;
String[] s;
Object[] t = (Object[]) s;

Any array, including int[] is actually an Object. This is why you can cast to Object. However, int is a primitive, so it doesn't extend Object, so you cannot cast to Object[].
