Class FizzBuzz

java.lang.Object
g1101_1200.s1195_fizz_buzz_multithreaded.FizzBuzz
public class FizzBuzz extends Object
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 ith 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 <= n <= 50
