使用Java中的helper函数获取数组中的索引(无参数)

public class ArrayHelper {
    // 获取数组长度的辅助函数
    public static int getArrayLength(Object[] array) {
        if (array == null) {
            throw new IllegalArgumentException("Array cannot be null");
        }
        return array.length;
    }

    public static void main(String[] args) {
        Integer[] numbers = {1, 2, 3, 4, 5};
        System.out.println("The length of the array is: " + getArrayLength(numbers));
    }
}
