8.Program to find the frequency of odd & even numbers in the given matrix
💡Code:
import java.util.Scanner; public class FrequencyOddEven7078 { public static void main(String[] args) { Scanner scanner = new Scanner(System.in); // Get the dimensions of the matrix from the user System.out.print("Enter the number of rows: "); int rows = scanner.nextInt(); System.out.print("Enter the number of columns: "); int columns = scanner.nextInt(); // Create the matrix int[][] matrix = new int[rows][columns]; System.out.println("Enter elements for the matrix:"); inputMatrix(matrix, scanner); // Find the frequency of odd and even numbers int oddFrequency = 0; int evenFrequency = 0; for (int[] row : matrix) { for (int element : row) { if (element % 2 == 0) { evenFrequency++; } else { oddFrequency++; } } } // Display the result System.out.println("Frequency of Odd Numbers: " + oddFrequency); System.out.println("Frequency of Even Numbers: " + evenFrequency); // Close the scanner scanner.close(); } // Function to input elements into a matrix private static void inputMatrix(int[][] matrix, Scanner scanner) { for (int i = 0; i < matrix.length; i++) { for (int j = 0; j < matrix[0].length; j++) { System.out.print("Enter element at position [" + (i + 1) + "][" + (j + 1) + "]: "); matrix[i][j] = scanner.nextInt(); } } } }
