I'm getting an error -- Error: Could not find or load main class Main -- Is there something I missed?

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

public class Main {
    public static void main(String[] args) {
        List<String> groceryLine = new ArrayList<>();
        //List<String> means a list of strings
        //I'm assuming you change whats in the arrows based in list type
        groceryLine.add("Jerome");
        groceryLine.add("Beth");
        groceryLine.add("Sam");

        System.out.println(groceryLine);

       groceryLine.remove(1);
       System.out.println(groceryLine);

       String jerome = groceryLine.get(0);
       System.out.println(jerome);
    }
}

I don't see anything wrong on my end. Do the file and the class have the same name? Meaning is it saved as Main.java?

Yes, they are the same name. I probably clicked the wrong thing before because it's now working. Thanks!
