如何从两个数组中创建一个新数组，并根据原始数组中的值初始化新数组

def create_new_array(arr1, arr2):
    if len(arr1) != len(arr2):
        return "Error: Arrays should have the same length."
    
    new_array = []
    for i in range(len(arr1)):
        if arr1[i] is not None and arr2[i] is not None:
            new_value = arr1[i] + arr2[i]  # 根据需求进行相应操作
            new_array.append(new_value)
        else:
            new_array.append(None)  # 根据需求设置默认值
    
    return new_array

array1 = [1, 2, 3, 4]
array2 = [5, 6, 7, 8]
result = create_new_array(array1, array2)
print(result)

import java.util.Arrays;

public class Main {
    public static void main(String[] args) {
        int[] array1 = {1, 2, 3, 4};
        int[] array2 = {5, 6, 7, 8};
        int[] result = createNewArray(array1, array2);
        System.out.println(Arrays.toString(result));
    }
    
    public static int[] createNewArray(int[] arr1, int[] arr2) {
        if (arr1.length != arr2.length) {
            System.out.println("Error: Arrays should have the same length.");
            return null;
        }
        
        int[] newArray = new int[arr1.length];
        for (int i = 0; i < arr1.length; i++) {
            if (arr1[i] != null && arr2[i] != null) {
                int newValue = arr1[i] + arr2[i];  // 根据需求进行相应操作
                newArray[i] = newValue;
            } else {
                newArray[i] = -1;  // 根据需求设置默认值
            }
        }
        
        return newArray;
    }
}
