public class Main {
    public static void main(String[] args) {
        List<Integer> numbers = Arrays.asList(1, 2, 3, 4, 5, 6, 7, 8, 9, 10);

        Map<Boolean, List<Integer>> result = numbers.stream()
                .collect(Collectors.partitioningBy(n -> n % 2 == 0));

        List<Integer> evenNumbers = result.get(true);
        List<Integer> oddNumbers = result.get(false);

        System.out.println("Even numbers: " + evenNumbers);
        System.out.println("Odd numbers: " + oddNumbers);
    }
}

Even numbers: [2, 4, 6, 8, 10]
Odd numbers: [1, 3, 5, 7, 9]
