Answer 1

The program written in Java is given in the explanation section

Step-by-step 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");

}

}
