无脑暴力简单不考虑其他因素，为完成而完成的解法

import java.util.Scanner;

public class Test{
    public static void main(String[] args) {
        Scanner in = new Scanner(System.in);
        int arr[][] = new int[3][3];
        //输入
        for (int i = 0; i < arr.length; i++){
            for (int j = 0; j < arr[i].length; j++){
                arr[i][j] = in.nextInt();
            }
        }
        //交换
        int num[][] = new int[3][3];
        for(int i = 0; i < arr.length; i++){
            for (int j = 0; j < arr.length; j++){
                num[i][j] = arr[j][i];
            }
        }

        //输出
        for (int i = 0; i < num.length; i++){
            for (int j = 0; j < num[i].length; j++){
                System.out.print(num[i][j]+" ");
            }
            System.out.println();
        }
    }
}
