Exam 9: Exception Handling

If you were going to catch an exception of type Exception,where should this catch block be placed within your code?

Define an exception class called NegativeNumberException.The class should have a constructor with no parameters.If an exception is thrown with this zero-argument constructor,getMessage should return "Negative Number Not Allowed!"
