Question

I would like to know what code to use to convert a double[] array into a string[] array

Answer 1

You’ll need to create a target array of equal size to the original array, and iterate over it, converting element by element.

Example:

double[] d = { 2.0, 3.1 };
String[] s = new String[d.length];

for (int i = 0; i < s.length; i++)
    s[i] = String.valueOf(d[i]);
