import java.util.Scanner; public class MatrixOperator { public static void main(String args[]) { int r1, c1, r2, c2, sum = 0, i, j, k; Scanner in = new Scanner(System.in); System.out.print("Enter number of rows and columns of first matrix : "); r1 = in.nextInt(); c1 = in.nextInt(); int first[][] = new int[r1][c1]; System.out.print("Enter first matrix elements : "); for(i=0 ; i<r1 i for j first in.nextint system.out.print number of rows and columns second matrix : r2="in.nextInt();" c2="in.nextInt();" if c1 the entered order can be multiplied.. else int new multiply elements k sum="sum" multiplication result is></r1> |
Output:
Enter number of rows and columns of first matrix : 2 2
Enter first matrix elements : 2 4 6 8
Enter number of rows and columns of second matrix :2 2
Enter second matrix elements : 3 6 9 12
Matrix multiplication result is :
42 60
90 132
Enter first matrix elements : 2 4 6 8
Enter number of rows and columns of second matrix :2 2
Enter second matrix elements : 3 6 9 12
Matrix multiplication result is :
42 60
90 132
That’s all about mutliplying two matrices in java.
