In this article, we will see FizzBuzz Program in Java. FizzBuzz is a most frequently asked question in interview. But, it is very simple. In FizzBuzz program, we print a series of positive integers from 1 to n. If any number is completely divisible by 3 and 5, then print "FizzBuzz" and if any number is only completely divisible by 3, then print "Fizz" and if any number is only completely divisible by 5, then prints "Buzz", otherwise prints that positive integer.
