This program plays the game "Fizzbuzz". It counts to 100, replacing each multiple of 5 with the word "fizz", each multiple of 7 with the word "buzz",
and each multiple of both with the word "fizzbuzz". It uses the modulo operator (%) to determine if a number is divisible by another.

Java Code:
public class FizzBuzz { // Everything in Java is a class

  public static void main(String[] args) { // Every program must have main()
  
    for (int i = 1; i <= 100; i++) { // count from 1 to 100
      if (((i % 5) == 0) && ((i % 7) == 0)) // Is it a multiple of 5 & 7?
        System.out.print("fizzbuzz");
      else if ((i % 5) == 0) // Is it a multiple of 5?
        System.out.print("fizz");
      else if ((i % 7) == 0) // Is it a multiple of 7?
        System.out.print("buzz");
      else
        System.out.print(i); // Not a multiple of 5 or 7
      System.out.print(" ");
    }

    System.out.println();

  }
