with a limited amount of time (20 minutes to talk,code,and discuss) and not wanted to google things, I wasnt made aware that I could sort the entry[] array by overriding its comparable method. this is the correct answer. Collections.sort(entries, new comparator()) { public int compare(entry e1, entry e2) { return Integer.compare(e1.TotalScore, e2.totalScore);
