Write a program that prompts the user to enter a number then counts the number of odd numbers and even numbers the user enter. The program should exit if the user enter a zero or a number less than zero. For example, if the user enters 4, 7, 9, 8 21, 22, -1; upon entering -1 the program displays/output "3 even numbers and 3 odd numbers" were entered, then the program terminate

The program written in Java is given in the explanation section

Explanation:

import java.util.Scanner;

public class num3 {

   public static void main(String[] args) {

       Scanner in = new Scanner(System.in);

       System.out.println("This program counts evens and odds");

       System.out.println("To exit enter ZERO  or a NEGATIVE number");

       int num = in.nextInt();

       int numEvens=0;

       int numOdds = 0;

        while(num>=1){

            if(num%2==0){

             numEvens++;

            }

            else{

             numOdds++;

               }

            System.out.println("Enter the next number");

            num = in.nextInt();

           }

           System.out.println(numEvens+" even numbers and "+numOdds+" odd numbers");

   }

}
