Question

How to create array of generic type? How does generic Arrays.copyOf() method work? It returns a copy of generic array. So it is possible to create generic arrays. But how? How one can write a method similar to copyOf()?

Answer 1

If you need to create it at runtime you need at least know the type at that very moment, so you could use the following approach:

a = (T[]) Array.newInstance(c,s);

where T is the generic type, c is the class of T and s is the initial size.
