[JAVA] Write FizzBuzz without using "="

I want to write FizzBuzz without using "="

There is no particular meaning Let's write up to 20 FizzBuzz in various languages without using "="

C language

c_fizzbuzz.c

#include <stdio.h>

int main(void) {
  int n;
  n++;
  while (1) {
    if (n%3 && n%5) {
      printf("%d", n);
    }
    else{
      if (!(n%3)) {
        printf("Fizz");
      }
      if (!(n%5)) {
        printf("Buzz");
      }
    }
    printf("\n");
    n++;
    if (n>20) {
      break;
    }
  }
  return 0;
}

Use that 0 is entered if not initialized (however, depending on the compiler) Conditional branch using the property that 0 is False and the others are True

Python

python_fizzbuzz.py

def fizzbuzz(n):
    if n%3 and n%5:
        return n
    else:
        if not n%3 and not n%5:
            return "FizzBuzz"
        elif not n%3:
            return "Fizz"
        elif not n%5:
            return "Buzz"

for x in list(map(fizzbuzz, range(1,21))):
    print(x)

Because Python has no increments Create a list of integers with range In the method of multiplying all functions at once with map Sober

print("hoge", end="")

It was hard because I couldn't use

Java

java_fizzbuzz.java

class java_fizzbuzz {
  static int n;
  public static void main(String[] args) {
    n++;
    while(true){
      if (!String.valueOf(n%3).equals("0") && !String.valueOf(n%5).equals("0")) {
        System.out.print(n);
      }
      else{
        if (String.valueOf(n%3).equals("0")) {
          System.out.print("Fizz");
        }
        if (String.valueOf(n%5).equals("0")) {
          System.out.print("Buzz");
        }
      }
      System.out.println();
      n++;
      if (n>20) {
        break;
      }
    }
  }
}

Take advantage of class member variables being initialized with 0 It turns out that Boolean is not processed with 0 or other By converting to String once and comparing with equals, it was not necessary to use equals

Summary

Please refer to it when you really do not want to use "=" Let's initialize the variables explicitly

There is a better way to write! You can do this in this language! If you have any questions, please leave a comment.
