Question

I read here @ java.sun that int[] iarr is a primitive array and int[][] arr2 is a object array. What is the difference between a primitive type and an object type ? How are the above two different from each other ?

Answer 1

int[] is a primitive array because it contains elements of primitive type int. Every array itself is Object, so array of primitives is object too.

int[][] is a array of int[], i.e. each element of int[][] contains array of integers. But since array is a object int[][] contains objects, not integers.
