Question

Input an int greater than 0 and print every multiple of 5 between it and 0 inclusive in descending order. If the number is not greater than 0 print "error". Print all numbers on one line with single spaces in between.
Example:
Enter a positive integer:
42
40 35 30 25 20 15 10 5 0

Answer 1

import java.util.Scanner;

public class JavaApplication42 {

   public static void main(String[] args) {

       Scanner scan = new Scanner(System.in);

       System.out.println("Enter a positive integer:");

       int num = scan.nextInt();

       if (num < 0){

           System.out.println("error");

       }

       else{

           while(num >=0){

               if (num %5 == 0){

                   System.out.print(num+" ");

               }

               num--;

           }

       }

   }

I hope this helps!
