Yet another boring FizzBuzz I've just finished my first program written in Java. It's a simple, boring, yet well-known FizzBuzz challenge where you have to:


  Write a program that prints the numbers from 1 to 100. But for
  multiples of three print “Fizz” instead of the number and for the
  multiples of five print “Buzz”. For numbers which are multiples of
  both three and five print “FizzBuzz”."


I know there are some other FizzBuzz questions here, but I'd really like to start learning Java in the right way, which means that I'm looking for:


Naming conventions
Coding standards and best practices


Coming from Python world, I was tempted to create a separate method named fizzBuzz() which I then called in my main() method. Is this a bit overkill for such a simple task?

package fizzbuzz;

class FizzBuzz {
/*
    Write a program that prints the numbers from 1 to 100. But for multiples of
    three print “Fizz” instead of the number and for the multiples of five print
    “Buzz”. For numbers which are multiples of both three and five print
    “FizzBuzz”."
 */

    public static void fizzBuzz() {
        for(int i = 1; i &lt;= 100; i++) {
            if (i % 3 == 0 &amp;&amp; i % 5 == 0)
                System.out.println("FizzBuzz");
            else if (i % 3 == 0)
                System.out.println("Fizz");
            else if (i % 5 == 0)
                System.out.println("Buzz");
            else
                System.out.println(i);
        }
    }

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

Well, it is a little bit too much for such a simple task, but it is a good habit to do so and if I were you I would stick to it.  



Overall your fizzBuzz looks good. 


Naming -> Check


but  


Best Practices -> Fail  


This is because you omitted braces {} although they are optional for single instruction if, else if and else branches.  

Omitting the braces can lead to hidden, and therefore hard to find bugs. I would like to encourage you to always use them.  

Another thing is that you have some magic numbers, like 1, 100, 3, and 5 in your code which should either be extracted to some meaningful named constants, or passed to the method as parameters.  

You could add a isDivisibleBy(int value, int divider) method as well to make the responsibilities clear.
