    Java

            List<Integer> lt = new ArrayList<>();
        List<Integer> temp = new ArrayList<>();
        IntStream.range(0, 4).forEach(i -> {
                    IntStream.range(0, 4).forEach(j -> {
                        temp.add(arr.get(i).get(j));
                        temp.add(arr.get(i).get(j + 1));
                        temp.add(arr.get(i).get(j + 2));
                        temp.add(arr.get(i + 1).get(j + 1));
                        temp.add(arr.get(i + 2).get(j));
                        temp.add(arr.get(i + 2).get(j + 1));
                        temp.add(arr.get(i + 2).get(j + 2));
                        lt.add(temp.stream().reduce(Integer::sum).get());
                        temp.clear();
                    });
                }
        );
        System.out.println(lt.stream().max(Integer::compare).get());
