## Shortest FizzBuzz Solution in Java?

( 3 min read )

Count from 1 to 100, and follow these rules:
- Print “Fizz” if the number is divisible by 3
- Print “Buzz” if the number is divisible by 5
- Print “FizzBuzz” if the number is divisible by 3 and 5

FizzBuzz: A fun interview question to ask any programmer, in just about any language It would seem like there are only a few solutions, but in reality, there are all kinds of approaches to solve this coding question.

### STOP!

If you haven’t tried this yet, go try it before looking at solutions!

My coworker recently brought up the question and was curious what the most concise solution in Java was. I took it as a challenge. Here is my latest solution in Java:

``````public static void fizzBuzzSolution2(){
// 92 characters without spaces
for(int i=1; i < 101; i++) {
System.out.println(i%15==0?"FizzBuzz":i%3==0?"Fizz":i%5==0?"Buzz":i);
}
}``````

I was quite impressed with my effort. 92 characters is half of my first attempt at FizzBuzz, 2 years ago, when I wrote a solution consisting of 186 characters. Of course, the total characters doesn’t include the spaces or method header, but those would be included in any solution, regardless.

``````public static void fizzBuzzSolution1(){
// 186 characters without spaces
for (int i = 1; i <= 100; i++) {
boolean flag = false;
if (i % 3 == 0) {
System.out.print("Fizz");
flag = true;
}
if (i % 5 == 0) {
System.out.print("Buzz");
flag = true;
}
if (!flag)
System.out.print(i);
System.out.println();
}
}``````

What’s your shortest solution in Java? I’m curious if my newest answer could be condensed down even further.

I should mention that with less characaters per method, the readability drops significantly. Which conflicts with one of the goals of Java programming; maintain human readability. Verbose solutions to FizzBuzz and other programming problems are not bad. But I find satisfaction when I’m able to solve a problem with the LEAST amount of code as possible.

One more thing; if you’re ever asked this question in a job interview, you shouldn’t fret about brevity in your solution. Especially if your interview is time-limited or being written on paper!
