Calculating the sum of all odd array indexes

Question

I want to calculate the sum of all odd array indexes, but I\'m having some trouble finding the right way to do it.

Here\'s my code so far:

    String id

Just edited your code:

String id = "9506265088085";
int[] intArray = new int[id.length()];
int sum = 0;

for (int i = 0; i < intArray.length; i++) {

    if (i%2!=0)
    {
        sum += Integer.parseInt(String.valueOf(id.charAt(i));

    }} 

    System.out.println(sum);
