can anyone help with this question?

a. Write the code to define the exception class called TornadoException. If the exception is thrown with the default constructor, use the correct method to return the message: "Tornado: Take cover immediately!" The other constructor has a single integer parameter m. If the exception is thrown with this constructor, use the correct method to return the message "Tornado: m miles away, and approaching!" b. Write a COMPLETE Java program test the TornadoException class in the above. -The tornado happens to be 8 miles away. -If the tornado is less than 5 miles away, we better take cover immediately; otherwise, we know that it is approaching
