Thanks Dawid!
bq. 2) cast superclass's array to (Object[]) first, then cast to the concrete
component type. Here:
I tried this, but couldn't get it to work:
{code}
class Example
{
public static class A<T> {
@SuppressWarnings("unchecked") // it is here for a reason :)
public T[] array = (T[]) new Object [1];
}
public static void main(String [] args)
{
A<Integer> clazzA = new A<Integer>();
System.out.println(((Integer[])((Object[])clazzA.array))[0]);
}
}
{code}
