    Static methods cannot reference generics defined on the class, static generic methods should be used. You can use it in Object[]之前加<T>表示这是一个静态泛型方法。使用静态泛型方法要在List<T>前面加<T> as follows

        public static <T>  List<T> name() {
            List<T> list = new ArrayList<T>();
            return list;
        }

    ...Generics are for definition, you need to specify the type when using them
