1. Declare a string list variable and immediately initialize it. Found an annoying bug in this one, as it needs to be declared as; ArrayList<> xxx = new ArrayList<>(); I personally used the List<> xxx = new ArrayList<>(); but this will not let it pass. (its even been mentioned in the lesson before this one by CodeGym itself :) ) Please fix it for future students! For the rest, i truly like the concept and enjoy everything else thusfar! great course, keep it up!
