  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;
  while(n>0){
  n=n-1;
  int m=ar[n];
  if(m%2==0){
  j=m+j;
  System.out.println(j);

  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.
