Here is the Java Code snippet.
- import java.util.Scanner;
- class MatrixMultiply {
- public static void main(String args[]) {
- int m, n, p, q, sum = 0, c, d, k;
- Scanner in = new Scanner(System. in );
- System.out.println("Enter the number of rows and columns of first matrix:");
- m = in .nextInt();
- n = in .nextInt();
- int first[][] = new int[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 number of rows and columns of second matrix:");
- p = in .nextInt();
- q = in .nextInt();
- if (n != p) System.out.println("Matrices with entered orders can't be multiplied with each other.");
- else {
- int second[][] = new int[p][q];
- int multiply[][] = new int[m][q];
- System.out.println("Enter the elements of second matrix:");
- for (c = 0; c < p; c++)
- for (d = 0; d < q; d++)
- second[c][d] = in .nextInt();
- for (c = 0; c < m; c++) {
- for (d = 0; d < q; d++) {
- for (k = 0; k < p; k++) {
- sum = sum + first[c][k] * second[k][d];
- }
- multiply[c][d] = sum;
- sum = 0;
- }
- }
- System.out.println("Resultant matrix after multiplication of two entered matrices:-");
