purpose of array with no subscript

[anderijk1]

I don't understand how this answer will not cause a compile or runtime problem. When is it okay to assign an array element to an array that has no subscript?

daa = daaa[0];

An assignment is ok only when the object you are assigning is of the same type as the type of the reference to which you are assigning.

So if daaa[0] refers to an array of the same dimensions as daa, then the assignment is ok. For example, if you have:
int[] ia = new int[]{ 1 };
int x = ia[0]; //here ia[0] and x are of same type i.e. int so it is ok.

int[][] iaa = new int[1][1]{ {1} };
ia = iaa[0]; here iaa is an array of array of ints but iaa[0] is an array of ints which is the same type as ia, so this is ok as well.

x = iaa[0]; this is not ok because x is not an array of ints, it is int.

Thank you very much for the excellent explanation.
