Question

java program to add two matrices

Answer 1

Heya,

here's ur answer

importjava.util.Scanner;
 
class AddingTwoMatrices
{publicstaticvoid main(String args[]){int m, n, c, d;
Scanner in =new Scanner(System.in);
 
System.out.println("Enter the number of rows and columns of matrix");
m = in.nextInt();
n = in.nextInt();
 
int first[][]=newint[m][n];int second[][]=newint[m][n];int sum[][]=newint[m][n];
 
System.out.println("Enter the elements of first matrix");
 
for( c =0; c < m ; c++)for( d =0; d < n ; d++)
first[c][d]= in.nextInt();
 
System.out.println("Enter the elements of second matrix");
 
for( c =0; c < m ; c++)for( d =0; d < n ; d++)
second[c][d]= in.nextInt();
 
for( c =0; c < m ; c++)for( d =0; d < n ; d++)
sum[c][d]= first[c][d]+ second[c][d];//replace '+' with '-' to subtract matrices
 
System.out.println("Sum of entered matrices:-");
 
for( c =0; c < m ; c++){for( d =0; d < n ; d++)System.out.print(sum[c][d]+"\t");
 
System.out.println();}}}

Hope u got it

Have a nice day ahead

Hola

Following is the program which can be used to add two matrices
...

public class MatrixAdditionExample{

  public static void main(String args[]){

  //creating two matrices    

int a[][]={{1,3,4},{2,4,3},{3,4,5}};   

 int b[][]={{1,3,4},{2,4,3},{1,2,4}};

 //creating another matrix to store the sum of two matrices    
int c[][]=new int[3][3]; 

 //3 rows and 3 columns      

//adding and printing addition of 2 matrices   
 for(int i=0;i<3;i++){ 

 for(int j=0;j<3;j++){

c[i][j]=a[i][j]+b[i][j];

 //use - for subtraction  System.out.print(c[i]
[j]+" ");
    }    
System.out.println();//new line   
 }    
}}  

hope u got it
