import java.util.Scanner;
public class CountEvenOddNumbersInArray
{
public static void main(String[] args)
{
Scanner sc = new Scanner(System.in);
int arrSize, a, countEven = 0, countOdd = 0;
System.out.println("Please enter number of elements of an array: ");
arrSize = sc.nextInt();
int[] arrNumbers = new int[arrSize];
System.out.println("Please enter " + arrSize + " elements of an array: ");
for(a = 0; a < arrSize; a++)
{
arrNumbers[a] = sc.nextInt();
}
for(a = 0; a < arrNumbers.length; a++)
{
if(arrNumbers[a] % 2 == 0)
{
countEven++;
}
else
{
countOdd++;
}
}
System.out.println("Total number of even numbers in an array java: " + countEven);
System.out.println("Total number of odd numbers in an array java: " + countOdd);
sc.close();
}
