Question

Write a while loop that prints all positive numbers that are divisible by 10 and less than a given number n. For example, if n is 100, print 10 20 30 40 50 60 70 80 90.

import java.util.Scanner;
public class PositiveLess {
   public static void main(String[] args) {
       Scanner in = new Scanner(System.in);
       System.out.print("n: ");
       int n = in.nextInt();
       ...
       while (...)
       {
           ...
       }
       System.out.println();
   }
}

import java.util.Scanner;
public class PositiveLess {
    public static void main(String[] args) {
        Scanner in = new Scanner(System.in);
        System.out.print("n: ");
        int n = in.nextInt();
        int i = 1;
        while (i<=n)
        {
            if (i % 10 == 0) {
                System.out.print(i+" ");
            }
            i+=1;
        }
        System.out.println();
    }
}
