Java Basic: Exercise-92 with Solution
Write a Java program to count the number of even and odd elements in a given array of integers.
Pictorial Presentation:
Sample Solution:
Java Code:
import java.util.*;
public class Exercise92 {
public static void main(String[] args)
{
int[] nums = {5, 7, 2, 4, 9};
int ctr_even = 0, ctr_odd = 0;
System.out.println("Original Array: "+Arrays.toString(nums));
for(int i = 0; i < nums.length; i++) {
if(nums[i] % 2 == 0)
{
ctr_even++;
}
else
ctr_odd++;
}
System.out.printf("\nNumber of even elements in the array: %d",ctr_even);
System.out.printf("\nNumber of odd elements in the array: %d",ctr_odd);
System.out.printf("\n");
}
}
Sample Output:
Original Array: [5, 7, 2, 4, 9] Number of even elements in the array: 2 Number of odd elements in the array: 3
