       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");

   }

}
