(Try it and see.) keyboard.nextLine(); 2 3 4 5 6 7 8 9 10 11 Exercise 12: Define an exception class called PowerFailureException. The class should have a constructor with no parameters. If an exception is thrown with this zero- argument constructor, getMessage should return Power Failure! The class should also have a constructor with a single parameter of type String. If an exception is thrown with this constructor, then getMessage returns the value that was used as an argument to the constructor. 13. Exercise 31: What is the output produced by the following program? What would the output be if the argument to exerciseMethod were 42 instead of 42? (The class NegativeNumberException is defined in Display 9.8, but you need not review that definition to do this exercise.)
