Question

(1) Read in a number from the user that is in the ranger 1-200. If the user inputs a number out of that range, print out:Invalid number, try again. and read in a number until a valid one is produced.

(2) Print out the numbers from 1 to userInput but:

If a number is divisible by 3, print Fizz instead

If a number is divisible by 5, print Buzz instead

If a number is divisible by both 3 and 5, print out FizzBuzz

Hint: What's the remainder if a number n is divisible by number m? That is, what would be the result of n % m?

import java.util.Scanner;

public class FizzBuzz {
public static void main(String[] args) {
  
//TODO: read in input from the user, making sure to check it's within range
  
  
//TODO: the loop to print 0-userInput
}
}

Answer 1

import java.util.Scanner;

public class FizzBuzz {
    public static void main(String[] args) {

        Scanner in = new Scanner(System.in);
        int n;
        while (true) {
            n = in.nextInt();
            if(n >= 1 && n <= 200) {
                break;
            }
            System.out.println("Invalid number, try again.");
        }

        for(int i = 0; i <= n; ++i) {
            if(i % 3 == 0 && i % 5 == 0) {
                System.out.println("FizzBuzz");
            } else if(i % 3 == 0) {
                System.out.println("Fizz");
            } else if(i % 5 == 0) {
                System.out.println("Buzz");
            } else {
                System.out.println(i);
            }
        }
    }
}
