It may be because you are declaring a List as a generic collection, but without specifying the type. You should do just what you did with the HashSet:

List<String> list = new List<String>(); // or Arrays.asList(text_arr);
HashSet<String> set = new HashSet<String>(list);

Hope it solves it.

  • List list = new List(); you cannot instantiate "new List();" , you should provide its implementation, like ArrayList<>(); – user_vs Mar 20 '18 at 04:39
