"<identifier> expected" in constructor method

Question

I'm just starting out with Netbeans and I ran into a problem trying to write a new class.

public class DeliveryList<T> extends ArrayList<T>
{
    public DeliveryList<T> // <identifier> expected
    {
    }
}

Netbeans throws this error at me and I'm not quite sure what to do.

Try this - read Java generics tutorial pages.

class DeliveryList<T> extends ArrayList<T>
{
  public <T>DeliveryList() {}
}

Oh wow. Forgot to add parentheses. Can you explain why putting the generic before the name makes it work though? I tried it the other way but no dice.
