$3.$ Write a statement that throws an instance of the exception class from #$2$ above.$$ Use a variable argument such as n or number if using the overloaded constructor. $$

$//$Code the statement.

$4.$ The instance method getValueFromFile is public and returns an int.$$ It accepts no arguments.$$ The method is capable of throwing a FileNotFoundException and an IOException in that order.$$

$//$Code the header for this method.$$

$$

$5.$ Write a block statement that calls the getValueFromFile method from #$4$ above.$$ Be sure to handle all the exceptions that the method can throw.
