Question

Write a Java program that will

- read two 2x3 matrices A and B.

- compute their sum (C=A+B)

- print out the C matrix

Please write out code. No screen shots please.

Answer 1

import java.util.Scanner;

public class MatrixTwoByThreeAddition {
  
public static void main(String args[]) {
  
int i,j;
  
int matxOne[][] = new int[2][3];
int matxTwo[][] = new int[2][3];
int matxSum[][] = new int[2][3];
  
Scanner input = new Scanner(System.in);
  
// Reading the Matrix One Element From User.
System.out.println("Enter values for Matrix (2*3) One");

for(i = 0; i < 2; i++)
{
for(j = 0; j < 3; j++)
{
matxOne[i][j] = input.nextInt();
System.out.println(matxOne[i][j]);
}
}
// Reading the Matrix Two Element From User.
System.out.println("Enter values for Matrix (2*3) Two");

for(i = 0; i < 2; i++)
{
for(j = 0; j < 3; j++)
{
matxTwo[i][j] = input.nextInt();
}
}
  
// Adding the values of MatrixOne and MatrixTwo
for(i = 0; i < 2; i++)
{
for(j = 0; j < 3; j++)
{
matxSum[i][j] = matxOne[i][j] + matxTwo[i][j];
}
}
  
// Display the sum of the Matrices
for(i = 0; i < 2; i++)
{
for(j = 0; j < 3; j++)
{
System.out.println(matxSum[i][j]+"\t");
System.out.println();
}
}
  
}
