Matrix Addition

Aim:

This webpage demonstrates a simple Java program that performs addition of two matrices.

Algorithm:

The algorithm is as follows:

  1. Take input for the number of rows and columns of the matrices.
  2. Initialize two matrices with the specified dimensions.
  3. Take input for the elements of both matrices.
  4. Add corresponding elements of both matrices and store the result in a new matrix.
  5. Display the resulting matrix.

Java Code:

import java.util.Scanner;

public class matrix {
    public static void main(String args[]) {
        Scanner s = new Scanner(System.in);
        System.out.println("Enter number of rows:");
        int rows = s.nextInt();
        System.out.println("Enter number of columns:");
        int columns = s.nextInt();
        int[][] a = new int[rows][columns];
        int[][] b = new int[rows][columns];
        System.out.println("Enter the first matrix");
        for (int i = 0; i < rows; i++) {
            for (int j = 0; j < columns; j++) {
                a[i][j] = s.nextInt();
            }
        }
        System.out.println("Enter the second matrix");
        for (int i = 0; i < rows; i++) {
            for (int j = 0; j < columns; j++) {
                b[i][j] = s.nextInt();
            }
        }
        int[][] c = new int[rows][columns];
        for (int i = 0; i < rows; i++) {
            for (int j = 0; j < columns; j++) {
                c[i][j] = a[i][j] + b[i][j];
            }
        }
        System.out.println("The sum of the two matrices is");
        for (int i = 0; i < rows; i++) {
            for (int j = 0; j < columns; j++) {
                System.out.print(c[i][j] + " ");
            }
            System.out.println();
        }
    }
}

Output:
