    }
}

Which method throws the second exception in the code in the accompanying figure?

nextInt

-1

Explanation / Answer

13) h3 - Because the input provided is not of integer type.

14) Rethrowing the same exception for the calling environment

15) The program throws an exception and proceeds to execute the finally block.
Because finally block is always executed and it is not necessary that catch follows try block.

16) NullPointerException and NumberFormatException

17)There must be one finally block. - There is always 1 finally block associated with try catch block

18)NullPointerException and IllegalAccessException occur at runtime . NoSuchMethodException is mostly caught at compile time but in few scenarios can occur at runtime also.

19)The class Throwable, which is derived from the class Object, is the superclass of the class Exception.

20)nextLine :- Because this returns the String value and not Integer Value
