问题描述

<pre lang="cs">package matrix;
import java.util.Scanner;

public class Main {
    private static Object numbers;
   
    public static void main(String[] args) {
        
   System.out.print("enter number for rows: ");
        Scanner in=new Scanner(System.in);
       int rows=in.nextInt();
          System.out.print("enter number for columns: ");
        int column=in.nextInt();
        int[][] a=new int[rows][column];
    int[][] b=new int[rows][column];
       for(int i=0;i<rows;i++){
            for(int j=0;j<column;j++){
        System.out.printf("enter numbers["+i+"],["+j+"]: ");
        int length1=in.nextInt();
               //  a[i][j]=in.nextInt();
             System.out.printf(" ");
             
             
     System.out.print("enter number for rows: ");
 
        int rows1=in.nextInt();
          System.out.print("enter number for columns: ");
        int column1=in.nextInt();
       
        int[][] c=new int[rows][column];
    int[][] d=new int[rows][column];
          
        for(int k=0;k<rows1;k++){
             for(int l=0;l<column1;l++){
        System.out.printf("enter numbers["+k+"],["+l+"]: ");
        int length2=in.nextInt();
               //  a[i][j]=in.nextInt();
             System.out.printf(" ");
                
             }
        }
    }
}
    }
}

推荐答案

如果您告诉代码这样做，则可以让用户输入该数字！为什么将a [i] [j]分配给行和列?您应该将扫描的值分配给a [i] [j].

you can let the user give the number if you tell the code to do so !!! why are assigning a[i][j] to rows and column????? you should assign the scanned value to a[i][j].
