java - <T>泛型为什么在Object[]的前面？为什么都是用t代替，下面的代码却报错？

Question

Answer 1

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;
    }

Answer 2

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