What is going on here?

I get the green checkmark that my code is correct in the editor section, but up top I get the Bummer error message. Note the part the for loop, it asks: Write a for-each loop to print out each dog name:

import java.util.ArrayList; import java.util.List;

public class Main {

public static void main(String[] args) {
    List<String> dogNames = new ArrayList<>();
    dogNames.add("Snoopy");
    dogNames.add("Rin Tin Tin");
    dogNames.add("Gloria");

   for (dogNames : dogNames) {
        System.out.println(name);
    }
}

Not sure what the checker is doing. But for the question you will want to read the line below what you edit

System.out.println(name)

and notice that name is the element in the loop. Try this instead:

for (String name: dogNames)
