java-如何使用两个2D数组计算2个数字的总和？

Question

I have to write a program which allows the input of two numbers in two 2*3 arrays and displays the sum of the corresponding numbers. I am not able to understand why and how the program is to be implemented using two 2*3 arrays so basically I am at a lost of how it should actually be working. But still here is what I have come up so far:

package lesson1;
import java.util.*;

class MyClass{
public static void main(String[] args) {

    Scanner input= new Scanner(System.in);

    int sum;

    int array1[][]= new int[2][3];
    int array2[][]= new int[2][3];

    for(int i=0; i<array1.length; i++){

        for(int j=0; j<array1[i].length; j++){

            array1[i][j]= input.nextInt();

            for(int x=0; x<array2.length;x++){
                for(int y=0; y<array2.length; y++){

                    array2[x][y]= input.nextInt();

                sum= array1[i][j]+ array2[x][y];
                System.out.println("The sum is "+sum);
                }

             }

            }


        }


         }           


    }

I believe that your code is too much complicated

At first you have two arrays, the array1 and the array2. That's fine but you don't need to create four " for "s, for that.

You can do

for (int i = 0; i < array1.length; i++) {
     for (int y = 0; y < array1[i].length; y++ {
         array1[i][y]= input.nextInt();
         array2[i][y]= input.nextInt();
         sum = sum + array1[i][y] + array2[i][y];
     }
}

to fill them up and sum them.
