Как удалить строку в массиве java

int[][] arr = {{1,2,3}, {4,5,6}, {7,8,9}};
                int rowToDelete = 1;
                
                int rows = arr.length;
                int columns = arr[0].length;
                int[][] result = new int[rows - 1] [columns];

                int j = 0;
                for(int i = 0; i < rows; i++) {
                    if (i != rowToDelete) {
                        result[j++] = arr[i];
                    }
                }

                System.out.println(Arrays.deepToString(result));  // => [[1, 2, 3], [7, 8, 9]]
