Shortest way to cast a 2d int array into 2d double

Question

I have a method which only gets double[][] to which I would like to pass int[][], is there a short way of doing this in java, something as simple as:

int [][] iArray = {
          { 1, 2, },
          { 5, 6, }
        };
double [][] dArray = (double[][]) iArray ; ???

Answer 1

Unfortunately the only way to cast your array is to iterate through each element and cast them one by one while re-inserting in your new double[][] array.

There is no shortcut.
