Output:
[12, 2, 43, 67, 4, 1, 23]
[I@5224ee


Output varies:
Isn't its answer that Integer class overrides the toString() method and in case of int[], Object class version of toString() used?

How all the values of Integer[] printed when we merely pass an reference variable. What happens inside the toString(), does it do complete traversal or use Iterator or something.

Please help!!!

Hi,

In the second case you prints the array not the list, so you will get the hashCode of the Object.

here is the toString mystification !
