Class FizzBuzz

public final class FizzBuzz

    1195 - Fizz Buzz Multithreaded.

    Medium

    You have the four functions:

    • printFizz that prints the word "Fizz" to the console,

    • printBuzz that prints the word "Buzz" to the console,

    • printFizzBuzz that prints the word "FizzBuzz" to the console, and

    • printNumber that prints a given integer to the console.

    You are given an instance of the class FizzBuzz that has four functions: fizz, buzz, fizzbuzz and number. The same instance of FizzBuzz will be passed to four different threads:

    • Thread A: calls fizz() that should output the word "Fizz".

    • Thread B: calls buzz() that should output the word "Buzz".

    • Thread C: calls fizzbuzz() that should output the word "FizzBuzz".

    • Thread D: calls number() that should only output the integers.

    Modify the given class to output the series [1, 2, "Fizz", 4, "Buzz", ...] where the <code>i<sup>th</sup></code> token ( 1-indexed ) of the series is:

    • "FizzBuzz" if i is divisible by 3 and 5,

    • "Fizz" if i is divisible by 3 and not 5,

    • "Buzz" if i is divisible by 5 and not 3, or

    • i if i is not divisible by 3 or 5.

    Implement the FizzBuzz class:

    • FizzBuzz(int n) Initializes the object with the number n that represents the length of the sequence that should be printed.

    • void fizz(printFizz) Calls printFizz to output "Fizz".

    • void buzz(printBuzz) Calls printBuzz to output "Buzz".

    • void fizzbuzz(printFizzBuzz) Calls printFizzBuzz to output "FizzBuzz".

    • void number(printNumber) Calls printnumber to output the numbers.

    Example 1:

    Input: n = 15

    Output: 1,2,"fizz",4,"buzz","fizz",7,8,"fizz","buzz",11,"fizz",13,14,"fizzbuzz"

    Example 2:

    Input: n = 5

    Output: 1,2,"fizz",4,"buzz"

    Constraints:

    • 1 &lt;= n &lt;= 50
