Hi Friend,

Try the following code:

import java.util.*;
class MatrixAddition{

    public static void main(String[] args){
     Scanner input = new Scanner(System.in);
    int[][] A = new int[3][3];
int[][] B = new int[3][3];
int[][] C = new int[3][3];
System.out.println("Enter elements for matrix A : ");
for (int i=0 ; i < A.length ; i++)
for  (int j=0 ; j < A[i].length ; j++){
A[i][j] = input.nextInt();
}
System.out.println("Enter elements for matrix B : ");
for (int i=0 ; i < B.length ; i++)
for  (int j=0 ; j < B[i].length ; j++){
B[i][j] = input.nextInt();
}
System.out.println("Matrix A: ");
        for (int i=0 ; i < A.length ; i++){
            System.out.println();
            for  (int j=0 ; j < A[i].length ; j++){
                System.out.print(A[i][j]+" ");
                  }
        }
System.out.println();
System.out.println();
System.out.println("Matrix B: ");
        for (int i=0 ; i < B.length ; i++){    
            System.out.println();
            for  (int j=0 ; j < B[i].length ; j++){
                System.out.print(B[i][j]+" ");
                  }
        }
System.out.println();
System.out.println();
System.out.println("Addition Of Matrices: ");
for(int i=0;i<3;i++){
for(int j=0;j<3;j++){
C[i][j]=A[i][j]+B[i][j];
System.out.print(C[i][j]+" ");
}
System.out.println();
}
}
}

Thanks
