  • They are references to the same stringbuilder – EpicKip Mar 17 '17 at 12:12

    @EpicKip No, the fine point is that `x` and `y` are distinct references to the same `StringBuilder`, and he is `null`(ing) only `x`. The `y` reference is still referencing the `StringBuilder` – xanatos Mar 17 '17 at 12:13
  • @xanatos While your explanation is more in depth and explain how the nulling works, my statement is still not incorrect :) – EpicKip Mar 17 '17 at 12:15
