First we must download the Java SE Development Kit from (http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html). Then install it. After that set the path variable. Next write the following code in any text editor and save it [with it’s class name.java] in a particular location . Open CMD and set the saved file location. Then write javac filename.java and press enter. Then type java filename and press enter. Program code: import java.util.Scanner; class MatrixMultiplication { public static void main(String args[]) { Scanner r = new Scanner(System.in); System.out.println("Enter the number of rows of first matrix"); int rowFM = r.nextInt(); System.out.println("Enter the number of columns of first matrix"); int colFM = r.nextInt(); int first[][] = new int[rowFM][colFM]; System.out.println("Enter the elements of first matrix"); int loop1, loop2; for ( loop1 = 0 ; loop1 < rowFM ; loop1++ ) { for (loop2 = 0 ; loop2 < co...
