In this article, we’ll talk about what is FizzBuzz and how to implement FizzBuzz in Java.
What is FizzBuzz?
FizzBuzz is a group game for children to understand the concept of division and multiplication. In which, each child counts the numbers (starting from 1) following these rules:
- if that number is divisible by ‘3’ then replace the number by word fizz.
- If that number is divisible by ‘5’ then replace the number by word buzz.
- In case that number is divisible with both the numbers then replace the number by word fizzbuzz.
So, if any child hesitates or makes a mistake then they have to leave the game.
Note: We can use any two numbers instead of 3 and 5.
Java FizzBuzz Program
Let’s see the implementation of Fizz buzz for first 100 numbers –
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 |
class FizzBuzz { public static void main(String[] args) { for(int i=1; i<=100; i++) { if(i%5 == 0 && i%3 == 0) System.out.print("FizzBuzz"); else if(i%3 == 0) System.out.print("Fizz"); else if(i%5 == 0) System.out.print("Buzz"); else System.out.print(i); System.out.print(", "); } } } |
Output:
1, 2, Fizz, 4, Buzz, Fizz, 7, 8, Fizz, Buzz, 11, Fizz, 13, 14, FizzBuzz, 16, 17, Fizz, 19, Buzz, Fizz, 22, 23, Fizz, Buzz, 26, Fizz …… till 100
Explanation:
In above program, we’re starting a loop from 1 to 100. Then we’re having three conditions:
- if i is divisible by both 3 and 5, then print FizzBuzz. If no then go for second condition.
- if i is divisible by 3 then print Fizz otherwise go for condition 3.
- if i is divisible by 5, print Buzz otherwise the number will be printed.
This question is one of the most asked questions in coding interviews.
