Exception Project

This assignment assumes you have completed Programming Challenge 1 of Chapter 11 (Employee and ProductionWorker Classes). Modify the Employee and ProductionWorker classes so they throw exceptions when the following errors occur:

• The Employee class should throw an exception named InvalidEmployeeNumber when it receives an employee number that is less than 0 or greater than 9999.

• The ProductionWorker class should throw an exception named InvalidShift when it receives an invalid shift.

• The ProductionWorker class should throw an exception named InvalidPayRate when it receives a negative number for the hourly pay rate.

Write a test program that demonstrates how each of these exception conditions works.

Programming Challenge 1

Employee and ProductionWorker Classes

Design a class named Employee. The class should keep the following information in fields:

• Employee name

• Employee number in the format XXX-L, where each X is a digit within the range 0-9 and the L is a letter within the range A-M.

• Hire date

Write one or more constructors and the appropriate accessor and mutator methods for the class.

Next, write a class named ProductionWorker that extends the Employee class. The ProductionWorker class should have fields to hold the following information:

• Shift (an integer)

• Hourly pay rate (a double)

The workday is divided into two shifts: day and night. The shift field will be an integer value representing the shift that the employee works. The day shift is shift 1 and the night shift is shift 2. Write one or more constructors and the appropriate accessor and mutator methods for the class. Demonstrate the classes by writing a program that uses a ProductionWorker object.
