A method that uses the Scanner class to obtain input does not require either catching or throwing an IOException. This is because
A) the Scanner class does not call upon any classes that throw checked exceptions
B) the Scanner class' methods call input methods in try statements and catch IOExceptions so that they are handled directly in the Scanner class
C) the Scanner class uses JOptionPane dialog boxes instead of java.io classes so that it does not have to deal with IOExceptions
D) the Scanner class overrides the class IOException making it an unchecked exception
E) none of the above, methods do require handling IOException even if thrown by a method in a Scanner class
