Review comment:
No need to cast, it was an example. In the method where the value is used
reference type is already `Object`, so we don't need to do a cast.
> Unless we wrap that single column in another array, the second form is the
same as:

Actually not, it will be the same as
```
addRow((Object) new Object[] {10, "foo"});
```
because method argument in `addSingleCol` has `Object` type.
