use Java 8 Stream API to find the sum of squares of all the odd numbers in an ArrayList

List<Integer> numbers = Arrays.asList(1, 2, 3, 4, 5, 6, 7, 8, 9);

int sumOfOddSquares = numbers.stream()

.filter(n -> n % 2 != 0) // Filter out even numbers

.mapToInt(n -> n * n) // Square each odd number

.sum(); // Sum the squared values

System.out.println(sumOfOddSquares); // Output: 165
