Oct 27, 4:58 AMhow 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);
}
}
}

Oct 27, 9:38 AMYou need to use a variable to keep track of the sum, and print it at the end, after the loop.

Jul 12, 3:35 PMint 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?

Jul 12, 7:11 PM@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.
