在java中如何将一个多维数组的维数传递给另一个多维数组？

public class Main {
    public static void main(String[] args) {
        int[][] array1 = {{1, 2, 3}, {4, 5, 6}, {7, 8, 9}};
        int[][] array2 = new int[array1.length][];
        
        for (int i = 0; i < array1.length; i++) {
            array2[i] = new int[array1[i].length];
            System.arraycopy(array1[i], 0, array2[i], 0, array1[i].length);
        }
        
        // 打印array2
        for (int i = 0; i < array2.length; i++) {
            for (int j = 0; j < array2[i].length; j++) {
                System.out.print(array2[i][j] + " ");
            }
            System.out.println();
        }
    }
}
