关于#java#的问题，如何解决？(开发工具-eclipse)

Question

就是要打印原数组也要打印互换的二维数组
运行结果:
123
456
789
147
258
369

import java.util.Scanner;

public class demo01 {
    public static void main(String[] args) {
        Scanner sc=new Scanner(System.in);
        System.out.println("请输入二维数组的列数");
        int n1=sc.nextInt();
        System.out.println("请输入二维数组的行数");
        int n2=sc.nextInt();
        //定义一个二维数组
        //原数组
        int [][]array1=new int[n1][n2];
        //行列互掉的二维数组
        int [][]array2=new int[n2][n1];
        System.out.println("请向数组中输入元素,从左向右，从上到下");
        for (int i = 0; i < n1; i++) {
            System.out.println("请输入第"+(i+1)+"行数据");
            for (int j = 0; j < n2; j++) {
                int x= sc.nextInt();
                array1[i][j]=x;
                array2[j][i]=x;
            }
        }
        //原来的二维数组
        System.out.println("原来的二维数组是:");
        for (int i = 0; i < n1; i++) {
            for (int j = 0; j < n2; j++) {
                System.out.print(array1[i][j]+" ");
            }
            System.out.println("");
        }
        //置换后的二维数组
        System.out.println("置换后的二维数组为:");
        for (int i = 0; i < n1; i++) {
            for (int j = 0; j < n2; j++) {
                System.out.print(array2[i][j]+" ");
            }
            System.out.println("");
        }
    }
