Creating an array of concrete instances of a generic class

Question

I have a generic class Position<E> and a concrete class Card. How do I create an array of type Position<Card>?

I tried: Position<Card>[] suitPositions = (Position<Card>[]) new Object[5];
but I get a ClassCastException.

But when I try: Position<String>[] suitPositions = (Position<String>[]) new Object[5];
it works just fine.

does `new Position[5]` not work? – Maljam Mar 06 '16 at 00:39 — Maljam, Mar 06 '16 at 00:39
No, that gives a Generic Array Creation error. – Mar 06 '16 at 00:41 — , Mar 06 '16 at 00:41
Use `(Position[])new Position>[5]`. – saka1029 Mar 06 '16 at 00:58 — saka1029, Mar 06 '16 at 00:58

Use the raw type to create the array:

Position<String>[] suitPositions = new Position[5];
