Question

I got a question about this program, it says: The FizzBuzz Challenge: Display numbers from 1 to x, replacing the word ‘fizz’ for multiples of 3, ‘buzz’ for multiples of 5 and ‘fizzbuzz’ for multiples of both 3 and 5. Th result must be:1 2 fizz 4 buzz fizz 7 8 fizz buzz 11 fizz 13 14 fizzbuzz 16 …

So my problem is at the time to print the output, I dont know what to do.

public class Multiplos {

    public static void main(String args[]) {

        for (int i = 1; i <= 100; i++) {

            if (i % 3 == 0) {
                System.out.print(i + " ");
                System.out.print(" fizz ");
            }

            if (i % 5 == 0) {
                System.out.print(" " + i);
                System.out.print(" " + "buzz ");
            }

            if((i % 3 == 0)&&(i % 5 == 0)){
                System.out.print(i + " ");
                System.out.print(" fizzbuzz ");
            }

        }

    }
}

Here’s the pseudocode:

for i in 1 to 100
   if(i % 5 == 0) AND (i % 3 == 0) print 'fizzbuzz'
   else if(i % 3 == 0) print 'fizz'
   else if(i % 5 == 0) print 'buzz'
   else print i

I’ll leave it as an exercise for you to convert it into Java, as that might help with the understanding as to how this works.
