FizzBuzz Problem

The FizzBuzz is an ancient word game. It is started to teach the children about division.
Now in many coding tests, it is a very popular challenge to solve the FizzBuzz problem.
In this problem, you have to print numbers from 0 to a certain range. But the problem is that you must have to print “Fizz” instead of the numbers which are divisible by 3 and “Buzz” instead of the numbers which are divisible by 5. But if a number is found to be divisible by both 3 and 5 then you must have to print “FizzBuzz” instead of the number.
Now let’s solve the FizzBuzz problem in Java

import java.util.*;

public class Codespeedy{
  public static void main(String[] args) {
    
    for(int i=0;i<=50;i++) {
      if(i%3==0 && i%5==0) System.out.println("FizzBuzz");
      else
      if(i%5==0) System.out.println("Buzz");
      else
      if(i%3==0) System.out.println("Fizz");
      else
      System.out.println(i);
      
    }
}
}

   Exactly the solution, a job interviewer or whoever doesn’t want to see.
   Not extensible at all if more words than “Fizz” and “Buzz” have to be added.
   One acceptable solution would be:

   for (int i = 0; i <= 50; i++) {
String output = "";
if (i % 3 == 0) output += "Fizz";
if (i % 5 == 0) output += "Buzz";
if (output.isEmpty()) output = Integer.toString(i);
System.out.println(output);
}

   and it would be even better to work with a Map and iterate through the entries.
