Finding the longest word ArrayList /Java

I want to write a method which finds the longest String (word). The output should be the longest word in case of two words with the same lenght the output should be: "More than one longest word".

I used ArrayList and almost had a solution, but something goes wrong. The case is that I have a problem when two words have the same lenght.
The output is :
More than one longest word
More than one longest word
14 incrementation is the longest word

Please check out piece of my code and help me to find the answer 🙂

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


    ArrayList<String> wordsList = new ArrayList<String>();
    wordsList.add("december");
    wordsList.add("california");
    wordsList.add("cat");
    wordsList.add("implementation");
    wordsList.add("incrementation");


    int largestString = wordsList.get(0).length();
    int index = 0;

    for (int i = 0; i < wordsList.size(); i++) {
        if (wordsList.get(i).length() > largestString) {
            largestString = wordsList.get(i).length();
            index = i;

        }else if(wordsList.get(i).length() == largestString){
            largestString = wordsList.get(i).length();
            index = i;
            System.out.println("More than one longest word");
        }
    }
    System.out.println(largestString +" " + wordsList.get(index) +" is the longest word ");


}

}

>Solution :

The fact is that you can’t tell what the biggest word until you have iterated once on all. Then you can iterate again to see the biggest one(s). Also it’s nicer to iterate on values rather then indices when possible

List<String> wordsList = Arrays.asList(
        "december", "california", "cat",
        "implementation", "incrementation");

int maxLength = Integer.MIN_VALUE;

for (String s : wordsList) {
    if (s.length() > maxLength) {
        maxLength = s.length();
    }
}
List<String> largestStrings = new ArrayList<>();
for (String s : wordsList) {
    if (s.length() == maxLength) {
        largestStrings.add(s);
    }
}

if (largestStrings.size() > 1) {
    System.out.println("More than one longest word");
    System.out.println(largestStrings);
} else {
    System.out.println(largestStrings.get(0) + " is the longest word");
}

Gives

More than one longest word
[implementation, incrementation]
