this global variable must go! Pass this data via parameter.
this text was my last nitpick. For hours I studied my code, my books, got nice ideas for solving other nitpicks, but not for this one. Then I studied other SortNames help cries on this site, but nobody had problems similar to mine! Or so it seems. The assignment says: "Load an ArrayList with Strings from a text file of names". Well, I did this, right in the second line of code after my "public class SortNames.." saying: Then I let the add() method of TextFileIn fill up this list. Then the main method (and other) take care of sorting and printing the stuff. If I have no ArrayList first thing, how can I fill it then?? WHAT parameter could pass it, and how?? Usually I always have SOME idea, but this time I feel like giving up on this. A leeettle tiny hint would be highly apreciated. Thank you, experienced folks.

I think the concept is to write a method that you pass an ArrayList to, populate the ArrayList in that method and return the ArrayList.

Hi Juliane, you said:

What add() method? I think the static attribute could be your problem -Barry

What if you make it a local variable rather than a class or member variable.

I should have said we should not use a static in this case
