[FIXED] Java convert String[] to int[]


I have a String[], where each element is convertible to an integer. What’s the best way I can convert this to an int[]?

int[] StringArrayToIntArray(String[] s)
    ... ? ...


public static int[] StringArrToIntArr(String[] s) {
   int[] result = new int[s.length];
   for (int i = 0; i < s.length; i++) {
      result[i] = Integer.parseInt(s[i]);
   return result;

Simply iterate through the string array and convert each element.

Note: If any of your elements fail to parse to an int this method will throw an exception. To keep that from happening each call to Integer.parseInt() should be placed in a try/catch block.
