Java Beginner; Compilation Error with "endsWith" method

I’m a beginner in Java and am kinda confused why the below code outputs a compilation error.

Below is the code.

What did I do wrong?

import java.util.Iterator;
import java.util.List;

public class Main {
    public static void main(String[] args) {
        List<String> words = List.of("Apple", "Bat", "Cat");

//        System.out.println("Apple".endsWith("le"));

        Iterator it = words.iterator();

        while (it.hasNext()) {
            if (it.next().endsWith("at")) {
                it.remove();
            }
        }

    }
}

>Solution :

You need to declare your iterator as Iterator<String> to tell the compiler it.next() will return a String, which has the endsWith, otherwise it will think it.next() will return an Object, which does not have endsWith.
