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!
