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;

But this does not:

Answer 1

A int[] is an array of primitives but also an Object itself. It is not an array of Objects

There is no auto-boxing support for arrays. You need to pick the right type of array to start with and not be converting it at runtime.
