Помогите решить задачу на Java)

 import java.util.Arrays; 
 
public class Main { 
 
    public static int[] getIntersection(int[] arr1, int[] arr2) { 
        int[] intersection = new int[Math.min(arr1.length, arr2.length)]; 
        int idx = 0; 
 
        for (int i = 0, j = 0; i < arr1.length && j < arr2.length; ) { 
            if (arr1[i] < arr2[j]) { 
                i++; 
            } else if (arr1[i] > arr2[j]) { 
                j++; 
            } else { 
                intersection[idx++] = arr1[i]; 
                i++; 
                j++; 
            } 
        } 
 
        return Arrays.copyOf(intersection, idx); 
    } 
 
    public static void main(String[] args) { 
        int[] numbers1 = {10, 11, 24}; 
        int[] numbers2 = {10, 13, 14, 18, 24, 30}; 
        int[] result1 = Main.getIntersection(numbers1, numbers2); 
        System.out.println(Arrays.toString(result1)); // => [10, 24] 
    } 
}
