Java Code :
** public static int hourglassSum(List> arr) {
int sum =0; List <Integer> arr1 = new ArrayList<>(); for(int i=0; i<4;i++){ for(int j=0; j < 4; j++){ sum = arr.get(i).get(j) + arr.get(i).get(j+1) + arr.get(i).get(j+2)+ arr.get(i+1).get(j+1)+ arr.get(i+2).get(j) + arr.get(i+2).get(j+1) + arr.get(i+2).get(j+2); arr1.add(sum);} }
return Collections.max(arr1); }
