Question

I\'m having problems with this code. I don\'t want to look at others, so I\'m wondering what\'s wrong with mine.

If we list all the natural numbers below 10 that are mu

Answer 1

If a number is a multiplier of both 3 and 5 (e.g.: 15, 30, 45, etc.), you will count it twice. So instead of two for loops, you should have one, with a complex condition:

public class Multiples {
    public static void main (String [] args) {
    int temp = 0;

    for (int i = 0; i < 1000; i++) {
        if (i % 3 == 0 || i % 5 == 0) {
            temp = temp + i;
        }

    }

    System.out.println (temp);
   }
}
