/* Program written in Java language using netbean 8.0 and JDK 1.8 */

package Main;

import java.util.Scanner;

public class OddEvenCount {
     public static void main(String[] args) {
        // Scanner class accept input from user
        Scanner scanner=new Scanner(System.in);
        int array[]=new int[100];// create maximum size array
        System.out.println("Enter Count of element for array :: ");
        int size=scanner.nextInt(); //get size from user and hold it in size
        System.out.println("Enter Elements for araay :: ");
        //get all entered elements in array
        for (int i = 0; i < size; i++) {
            array[i]=scanner.nextInt();
        }
        int evencount=0;
        int oddcount=0;
        //travel all element again for counting odd and even elemets
        for (int i = 0; i < size; i++) {
            if(array[i]%2==0){//condition for even element
                evencount++;
            }
            else//otherwise element is odd
                oddcount++;
            }
        System.out.println("Odd Elements count is ::"+oddcount);
        System.out.println("Even Elements count is ::"+evencount);
        }
      
    }
    /*

output

Enter Count of element for array ::
10
Enter Elements for araay ::
1 3 19 50 4 10 75 20 68 100
Odd Elements count is ::4
Even Elements count is ::6
