when you calculate even sum you have typo error num(13) should be 12 also you can use for loop to calculate sums: for(int i=0; i<num.length; i++){ if(i%2==0) sumEven =sumEven+num[i]; else sumOdd =sumOdd+num[i]; }

int[] nums = new int[15];
for(int i = 0; i < nums.length; i++) {
    // loop body
}

Got task right but code i used i lengthy. Can someone show me how a for loop would have been used here? Thanks
