Hey I have a Question, for my plugin (kits), I was wondering if I should use a hashmap instead of an arraylist because I am trying to make it so that one a player who performs a command can get certain things... -Example- I want it so that only the kit vipers(Poison sword) diamond sword, is the only diamond that does that. Well I am running into a problem where every kit can do that now. I am using the arraylist (thought it would seperate it) but would a hashmap do that?? Sorry I am learning java, my only source of help is from youtube. And I learning java from bukkit. EDIT by Moderator: merged posts, please use the edit button instead of double posting.
