public static int arr) {
int rows = arr.size(); // Corrected to use size() for List
int col = arr.get(0).size(); // Corrected to use size() for List inside List
int maxSum = Integer.MIN_VALUE; // Corrected variable naming

for (int i = 0; i < rows - 2; i++) {
for (int j = 0; j < col - 2; j++) {
int currSum = 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);
maxSum = Math.max(currSum, maxSum);
}
}
return maxSum;
}
