  • how do I print the sum?

    public class Main{
    static void doStuff(int[] ar){
    for (i=1; i<ar.length; i++) {
    if (i%2==0) {
    System.out.println(sum ar);

  • You need to use a variable to keep track of the sum, and print it at the end, after the loop.

  • int j=0;
    int n=ar.length;
    int m=ar[n];

    I'm not too sure why my code isn't working? Can I get a hint?

  • @Bernard, make sure you print the sum outside the loop. Also, to make things clearer, you could use a for loop instead of a while loop.
