A Method That Uses the Scanner Class to Obtain Input

question 14

Multiple Choice

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's 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 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 IOExceptions even if thrown by a method in a Scanner class
