Solution in Java

public class FizzBuzz {

    public static void main(String[] args) {
        printFizzBuzz(100);
    }

    public static void printFizzBuzz(int n) {
        for (int i = 1; i <= n; i++) {
            System.out.println(fizzBuzz(i));
        }
    }

    public static String fizzBuzz(int number) {
        String res = "";
        if (divBy(number, 3)) res += "Fizz";
        if (divBy(number, 5)) res += "Buzz";
        if (res.equals("")) return String.valueOf(number);
        return res;
    }

    public static boolean divBy(int first, int by) {
        if (by == 0) return false;
        int result = first / by;
        if (result * by  == first) return true;
        return false;
    }
