How do I override the toString method to display elements in a list in Java?

Question

I have been trying to figure this out for hours, but I am unable find an answer that works.

For completeness, I have posted the entire code below. If I do not Override

Answer 1

Just call toString() with the List element itself. Like so:

import java.util.List;
import java.util.LinkedList;
public class WordList {
    List list = new LinkedList();
    public static void main(String []args) {
       System.out.println(new WordList());
    }

    @Override
    public String toString() {
        String result = "";
        list.add("Hello");

        list.add("World");
        for (int i = 0; i < list.size(); i++) {
            result += " " + list.get(i).toString();//call toString on element of the list
        }
        return result;
    }
}

Output: ' Hello World'
