Title: Have code example use generic type that is actually defined in the code ...

...(i.e. Element) instead of one that is not previously defined (i.e. T).

The example is a little outdated as `Set.contains()` is inherited from `Collection` and it is no longer defined like that, but the code still gets the point across.
