what is wrong with this code, and what should it be?

import java.util.*;

public class Main {

List fizzBuzzList = new ArrayList<>(100);

public void fizzBuzzIterator(){

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

if (((i % 3) == 0) && ((i % 5) == 0)) {

fizzBuzzList.set(i, "FizzBuzz");

}

else if ((i % 3) == 0){

fizzBuzzList.set(i, "Fizz");

}

else if ((i % 5) == 0) {

fizzBuzzList.set(i, "Buzz");

}

else {

fizzBuzzList.set(i - 1, fizzBuzzList.get(i));

}

}

}

public static void main(String[] args){

for(int k = 0; k < fizzBuzzList.size(); k++){

System.out.println(fizzBuzzList.get(k));

}

}

}
