    Default Java Program for Matrix Multiplication

    I have composed a java program to play out a simple matrix multiplication. For framework duplication the section of the primary grid ought to be equivalent to the line of the subsequent network, then no one but we can perform matrix multiplication.

    package com.example.demo;
     
    public class MatrixMultiplication {
     
            public static void main(String[] args) {
     
                    int a[][] = {{1,2,3},{4,5,6},{7,8,9}};    
     
                    int b[][] = {{1,2,3},{4,5,6},{7,8,9}};    
     
                    int c[][] = new int[3][3];  //rows - 3 and columns -3 
     
                    for (int i = 0; i < 3; i++) {    
     
                           for (int j = 0; j < 3; j++) {    
     
                                     c[i][j] = 0;      
     
                                     for (int k = 0; k < 3; k++) {      
     
                                           c[i][j]+= a[i][k]*b[k][j];      
     
                                     } 
     
                                     System.out.print(c[i][j]+" ");   
                             } 
     
                            System.out.println(); 
                    }    
            }
    }

    What would be the output of this program?

    Can you explain what you are asking for?
    Do you have a problem with compiling and executing the code?
    If so, please copy any error messages and paste them here with your questions.

    Please edit your post and wrap your code with code tags:

    [code]
    **YOUR CODE GOES HERE**
    [/code]

    to get highlighting and preserve formatting.
    If you don't understand my answer, don't ignore it, ask a question.
