java中数组中的负数和正数分区

public class ArrayPartition {
    public static void main(String[] args) {
        int[] array = {1, -2, 3, -4, 5, -6, 7, -8, 9, -10};
        
        ArrayList<Integer> positiveNumbers = new ArrayList<>();
        ArrayList<Integer> negativeNumbers = new ArrayList<>();
        
        for (int num : array) {
            if (num >= 0) {
                positiveNumbers.add(num);
            } else {
                negativeNumbers.add(num);
            }
        }
        
        System.out.println("Positive numbers: " + positiveNumbers);
        System.out.println("Negative numbers: " + negativeNumbers);
    }
}
