Answer 3

Down casting objects is where you cast something to the type of a child class.
An example from Android:
TextView t = (TextView) getViewById(id);

The method returns a View, but here we specifically want a TextView, which is a class that extends View. Without the cast this will not compile because a View is not necessarily a TextView, but we can downcast the type to indicate that we are expecting a TextView from this call
