Convert a generic list to an array

Question

I have searched for this, but unfortunately, I don\'t get the correct answer.

class Helper {
    public static  T[] toArray(List list) {
           


        

Answer 1

You can't instantiate a Generic type like you did here:

 T[] array = (T[]) new Object[list.size()];

As, if T is bounded to a type, you're typecasting the new Object array to a bounded type T. I would suggest using List.toArray(T[]) method instead.
