Before catching an exception it is must to be thrown first.
This means that there should be a code somewhere in the
program that could catch the exception. We use throw
statement to throw an exception or simply use the throw
keyword with an object reference to throw an exception. A
single argument is required by the throw statement i.e. a
throwable object.
