Thread: Conditional Statement Issue *Newbie Help*

I'm trying a basic challenge that involves a program counting to 100, and displaying that output while it counts up.

• For every multiple of 3; it must print Fizz
• For every multiple of 5, it must print Buzz
• For every multiple of 3 & 5 it must print FizzBuzz

The code I've written handles System.out on the non-multiple numbers, and the FizzBuzz multiples without issue. However, for the multiples of just 3 and 5 it acts as if I didn't write any "else if" condition. I have been unable to figure out what might be causing this! Here is the code.

class prog{
	public static void main(String args[]){
 
	int num = 0;
 
	while (age < 100){
	num++;
 
	if (num % 3 != 0 || num % 5 != 0){
		System.out.println(num);
	}
	else if (num % 3 == 0 && num % 5 != 0){
		System.out.println("Fizz");
	}
	else if (num % 5 == 0 && num % 3 != 0){
		System.out.println("Buzz");
	}
	else if (num % 5 == 0 && num % 3 == 0){
		System.out.println("FizzBuzz");
	}
 
	}
 
 
	}
}

These two blocks

else if (num % 3 == 0 && num % 5 != 0){
System.out.println("Fizz");
}
else if (num % 5 == 0 && num % 3 != 0){
System.out.println("Buzz");

It's as if I never even wrote the code in.

Ex.
1,2,3,4,5 .... 13,14,FizzBuzz

When I'm trying to get 1,2,Fizz,4,Buzz....

Here's the error:

if (num % 3 != 0 || num % 5 != 0) {
                System.out.println(num);
            }

It must be

if (num % 3 != 0 && num % 5 != 0) {
                System.out.println(num);
            }

You see, this condition goes before your "Fizz" and "Buzz" conditions. But "Fizz" is executed only if num % 5 != 0. And if this condition is true, than the erroneous block's condition holds (that is, num % 3 != 0 || num % 5 != 0). The same thing is for the "Buzz" block.

That makes perfect sense. I can't believe I didn't pick up on that at all. Thanks!
