3. RetailItem Exceptions Programming Challenge 4 of Chapter 6 required you to write a RetailItem class that holds data pertaining to a retail item. Write an exception class that can be instantiated and thrown when a negative number is given for the price. Write another exception class that can be instantiated and thrown when a negative number is given for the units on hand.
Demonstrate the exception classes in a program.

For each method, you will also be required to create docstring as follows:
/**
* @param String as args
* @return Termination code as int, 0 for normal, anything else is error condition
* @throws Nothing is implemented
*/

Choose any program from this semester that accesses a file, but that does not use try-catch blocks to handle file not found exceptions. The program may be one you wrote or a sample provided by your instructor. Add a try and catch block to take the exception. You can decide what the handler does. It could simply print a message – such as on the screen in the IDE or a JOptionPane error message dialog box – or it could allow the user to enter the correct file name. Add comments to the beginning of the project code describing what you did and how it works.
Write a Month class that holds information about the month. Write exception classes for the following error conditions:• A number less than 1 or greater than 12 is given for the month number.• An invalid string is given for the name of the month.Modify the Month class so that it throws the appropriate exception when either of these errors occurs. Demonstrate the classes in a program.
