Question

Functions can return a string, not just an int or a float. Write a function called everOrOdd which takes an integer parameter and returns either "Even" or "Odd" based on the value passed. In main, prompt the user for a number, called num, then pass num to evenOrOdd and display the returned value on the screen. Keep doing this until the user enters a zero. Use the following run as an example:

Enter a number: 11

Odd

Enter a number: 12

Even

Enter a number: 13

Odd

Enter a number: 0

Answer 1

//EverOrOdd.java
import java.util.Scanner;
public class EverOrOdd {
    public static String everOrOdd(int n){
        if(n%2==0){
            return "Even";
        }
        else{
            return "Odd";
        }
    }

    public static void main(String[] args) {
        Scanner scanner = new Scanner(System.in);
        int n;

        System.out.print("Enter a number: ");
        n = scanner.nextInt();

        while (n!=0) {
            System.out.println(everOrOdd(n));
            System.out.print("Enter a number: ");
            n = scanner.nextInt();
        }
    }
}
