What does the following Java code output?

import java.util.LinkedHashSet;
import java.util.Set;
public class Main {
    public static void main(String[] args) {
        Set<String> order = new LinkedHashSet<>();
        order.add("First");
        order.add("Second");
        order.add("Third");
        System.out.println(order.iterator().next());
    }
}
