I still think, it would be more clear to speak about classes here rather then about types.
         Number[] na = new Integer[123];
         na[0] = new Integer(456);
         Integer[] ia = (Integer[])na.clone();

na is of type Number[]
ia is of type Integer[] and too of type Number[]
but ia contains object of class Integer[]
