  • Java Program to Add, Subtract, Multiply two matrices using switch statement. The program must also validate the sizes of two matrices before performing any operation and should raise exception in case the operation cannot be performed.

    import java.util.Scanner; public class MatrixOperations { public static void main(String[] args) { Scanner scanner = new Scanner(System.in); System.out.println(“Enter the number of rows and columns of the first matrix:”); int rows1 = scanner.nextInt(); int cols1 = scanner.nextInt(); int[][] matrix1 = new int[rows1][cols1]; System.out.println(“Enter the elements of the first matrix:”); for (int i = 0; i <…
