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();
}
}
}
}
