3. Code implementation （Java）

// Ideas 1———— simulation 
class Solution {
    
    public List<String> fizzBuzz(int n) {
    
        List<String> answer = new ArrayList<>();
        for (int i = 1; i <= n; i++) {
    
            if (i % 3 == 0 && i % 5 == 0) {
    
                answer.add("FizzBuzz");
            } else if (i % 3 == 0) {
    
                answer.add("Fizz");
            } else if (i % 5 == 0) {
    
                answer.add("Buzz");
            } else {
    
                answer.add(i + "");
            }
        }
        return answer;
    }
}
