Java Data Type - 如何旋转字符串

import java.util.Scanner;

public class Main {
  public static void rotate(char[][] original) {
    char[][] rotated = new char[3][3];
    for (int i = 0; i < 3; i++) {
      for (int j = 0; j < 3; j++) {
        rotated[i][j] = original[j][i];
      }
      System.out.println("\n");
    }
    for (int i = 0; i < 3; i++) {
      for (int j = 0; j < 3; j++) {
        System.out.print(rotated[i][j]);
      }
      System.out.println("\n");
    }
  }
  public static void main(String[] args) {
    char[][] original = new char[3][3];
    Scanner s = new Scanner(System.in);
    System.out.println("Enter values: ");
    for (int i = 0; i < 3; i++) {
      for (int j = 0; j < 3; j++) {
        original[i][j] = s.next().charAt(0);
      }
    }
    rotate(original);
  }
}
